Maintaining Optimum Climate Control in the Greenhouse for Plant Success - Gothic Arch Greenhouses The warming weather is a reminder to [url=http://www.xinhegreenhousefactory.com/greenhouse/]greenhouse[/url] owners to examine climate control strategies inside the structure so as to ensure crops grow strong and healthy throughout the warmer days and nights ahead. Without such consistency, plant damage and even death can occur. The experts at Gothic Arch Greenhouses, a family owned and operated greenhouse and supply business for nearly 70 years, can partner particular circumstance with quality, affordable, easy to use equipment needed to help ensure optimum climate control inside the greenhouse. “It boils down to three things,” says William H. “Buzz Sierke, third generation president of the Gulf Coast based business, “correct lighting, temperature and humidity. To know those, you first must know what conditions are needed for the particular plants being grown in the greenhouse.” Sierke encourages all growers, commercial or hobbyist, to think about where a particular plant originates. Take ornamentals and tropicals for example. Ornamentals can tolerate nighttime temps as low as the mid-50’s while that temperature can damage tender tropicals that don’t want it below 60 degrees. On the other hand, temperature needs for successful seed germination varies as do those of cool or warm weather vegetables. “It all depends on what you’re trying to grow, and under what circumstances,” Sierke says. Rising temps means higher humidity which, for some crops like Tropicals, is good, for others like some ornamentals, it could be deadly. If the circumstance calls for decreasing humidity levels inside the greenhouse, venting or exhausting the humid air is in order. That means air movement. A closed greenhouse needs a fan to blow hot stale air out of the structure and bring fresh cooler air inside via intake shutters mounted on the opposite end of the structure to create consistent environmental control. Gothic Arch Greenhouses offers a huge selection of greenhouse ventilation fans like our favorite, the Air Flow HAF fan, a specialized greenhouse fan that allows adjustable air patterns to create a uniform temperature throughout the structure to suit any growing need. According to Sierke, the Air Flow HAF is by far, the most versatile, energy efficient, best valued HAF fan available. For larger greenhouses, Sierke says the same optimum growing conditions can be maintained by using [url=http://www.xinhegreenhousefactory.com/greenhouse-system/greenhouse-cooling-system/]greenhouse cooling system[/url] which utilizes the hot air inside the greenhouse to evaporate the moisture from plant surfaces thus cooling the inside temps by up to 20 degrees. Whatever environmental control system you choose, you’ll need control. [url=http://www.xinhegreenhousefactory.com/greenhouse/arch-greenhouse/]Arch Greenhouse[/url] can help you choose from a wide selection of the most reliable automatic one, two, or manual variable speed thermostat controls available on the market today, designed especially for greenhouses. And no environmental control plan would be complete without a timer to give freedom over how much or how little light plants get and when. The right automatic timer allows control over automated watering and mist systems, fans, heaters, and other equipment too, allowing one time for other activities. So, as the days grow longer and warmer, take the time now to plan how to create and maintain consistent optimum growing conditions needed for successful healthy plant growth inside the greenhouse during the days ahead. Gothic Arch Greenhouses is the most trusted name in greenhouses with over 70 years of dependable service providing made in the USA, do-it-yourself greenhouse kits, related accessories, and the right environmental control systems to fit any need. Most of the greenhouses in the Netherlands are so-called Venlo greenhouses. This construction is strong, allows a lot of light to pass through, is relatively inexpensive. The [url=http://www.xinhegreenhousefactory.com/greenhouse/venlo-greenhouse/]Venlo greenhouse[/url] is ideal for the Dutch climate conditions. But which design fits in another climate, such as a desert or a humid climate? The Greenhouse Horticulture & Flower Bulbs Business Unit of Wageningen University & Research developed a method for designing one based on local conditions: Adaptive Greenhouse Design. An interactive tool demonstrates the operation and benefits of this method. The Freshteq Fieldlab offers companies and organizations a breeding ground for the development of innovative applications for international horticulture. Within the Freshteq Fieldlab – based in the World Horti Center in Naaldwijk – there are various activities and initiatives. ERDF Freshteq is made possible in part by the European Regional Development Fund (ERDF). A tool to predict how a crop will grow under certain conditions An example of the Freshteq initiatives is the Adaptive Greenhouse Design tool, an online tool developed by WUR. With the tool, an optimal greenhouse design can be made for a specific region. Today, more than two-thirds of new greenhouse construction is covered with film plastic. Besides the obvious advantages of low-cost, low taxes, ease of covering, four year life and additives such as anti-drip and light diffusion, there are other properties that should be considered when purchasing the material. [url=http://www.xinhegreenhousefactory.com/]Manufactures[/url] have worked hard to provide a material that will give good service, high light transmission and properties that improve plant production. Most greenhouse polyethylene film is manufactured as a coextrusion of three or more layers with different polymers and additives. Each of these layers contributes to the quality of the film by adding tear and puncture resistance, high light transmission, IR retention, UV blocking, dust control and color pigments. The following reviews some of these often overlooked properties that could influence your purchase decision. Thermicity A plastic film is considered an infrared film (IR) if less than 25% of the heat generated within the greenhouse is allowed to escape. The lower the percentage, the lower the winter heating bill. Regular greenhouse grade polyethylene film allows 30% to 60% of the IR heat to escape. Plastic manufacturers have found that mineral based additives, such as ethyl vinyl acetate (EVA), calcined kaolin clay or synthetic aluminum silicate can reduce the radiation loss. This material is usually added as one of the inner layers in the copolymer. These additives may reduce light transmittance slightly but they also diffuse the light spreading it evenly inside the greenhouse reducing shadows and allowing more light to reach lower into the canopy. It also helps to average out leaf temperatures at the top of the plant canopy reducing the amount of shading needed. Flammability Often building officials question a grower applying for a building permit as to the flammability of the film plastic. Section 3102.3 of the International Building Code states that “Plastic less than 20 mil thickness or located less than 30 feet above the floor as used in greenhouses where occupancy by the general public is not authorized is not required to meet the fire propagation performance criteria of NFPA 701 (National Fire Protection Association)”. Low density polyethylene plastic is an oil-based product with a high heat value of about 20,000 Btu/pound. It will burn if in contact with an external flame but does not maintain a flame by itself for very long. The additives used in copolymers could affect this some so obtaining the test results from the manufacturer may be necessary. Also copolymer film may not get building official approval for retail greenhouses. Photoselective films This [url=http://www.xinhegreenhousefactory.com/greenhouse-material/greenhouse-film/]greenhouse film[/url] absorbs or reflects specific wavelengths of light. They can enhance plant growth, suppress insects and diseases and affect flower development. Red films such as Dupont IR and Smartlite Red film reduce PAR light and create a shading effect. They have also been shown to improve rose yield and quality. Disease Control Plastic film manufacturers have developed disease control films that absorb UV radiation in the 340 to 390 nm wavelengths. These have been found to reduce the population of insects such as whiteflies, thrips miners and aphids. The material can also control the spread of certain diseases such as botrytis. As bees need UV to navigate, if you are using bees to pollinate plants in the greenhouse, purchasing a film that allows some of the UV part of the light energy spectrum to pass through may be important. Off-gassing from film Recent research by Dr Sarah-Jeanne Royer at the University of Hawaii in Manoa has found that LDPE film produces methane and ethylene gas when exposed to sunlight. In large poly covered ranges the amount of gas produced may be significant. As these gases can affect plant growth, additional research is needed to determine the level that may have an effect.

Quick guide: components for industrial packaging machines
Описание: Quick guide: components for industrial packaging machines The quality of the components you choose will play an important part in the life of your packaging equipment. Your packaging machine parts might rely on everything from cable ties and PCB mounting hardware to clamping levers and screw-on rubber bumper feet. Choose your components wisely and you can deliver a semi-automated or automated packaging machine that performs for years. This guide is designed to help you make those choices. We’ll focus on three types of packaging machines, but most of the components shown for each can be used on all machines, such as steel packing machine, cardboard box packing machines, carton wrapping machines, and sheet packing machines. Free samples and CAD downloads To make your job easier, we’ve made available free samples on most of our solutions, so you can try before you buy. You can also download free CADs of our solutions to help with designing your project. Strapping machine components Sometimes called banding strapping machines, they tension, seal and cut the strapping in one motion. Your design will depend on the strapping demand. Whether your application will be a pallet strapping machine, box strapping machine or another type, consider the recommendations below, which are ideal for semi-automatic or automatic strapping machines. Where relevant, the components you use should not only help the machine’s performance but contribute to health and safety, so consider insert glides and recessed handles. Your strapping machine also needs protecting. Use caps and plugs to protect critical profiles from damage during handling and transportation. You can also get a professional finish by using high-temperature masking for holes and contact points with easy-to-fit caps and plugs. Steel pipe stacking machine, also called stackers, are the most important lifting and transportation equipment in a three-dimensional warehouse and a symbol that represents the characteristics of a three-dimensional warehouse. The main function of the stacking crane is to move back and forth in the aisle of the three-dimensional warehouse, store the goods at the entrance of the roadway into the compartment of the shelf, or take out the goods in the compartment and transport it to the entrance of the roadway. The early stacker cranes hung a mast (column) on the lifting trolley of the bridge crane, and used the up and down movement of the fork on the column and the rotation of the column to carry goods, usually called the bridge stacker. Roadway stackers appeared in the United States around 1960. This stacker uses ground rails to prevent tipping. Since then, with the development of computer control technology and automated three-dimensional warehouses, stackers have become more and more widely used, with better technical performance and higher heights. Today, the height of the stacker can reach 40 meters. In fact, if it is not restricted by warehouse construction and cost, the height of the stacker can be higher. What is strapping? Strapping is the process of applying a steel or plastic strap around a product or pallet to bundle, reinforce, or attach it to something. This is done using a strapping machine (banding machine) such as steel belt strapping machine or strapping tool. Strapping machines can be divided into semi-automatic strapping machines, (fully) automatic strapping machines and pallet strapping machines. Strapping tools can be divided into hand strapping tools and battery & pneumatic strapping tools. The purpose of strapping products is to transport and / or store them quickly and undamaged in an efficient and safe manner. How does strapping work? The strapping band is applied horizontally or vertically around the product, with the ends of the strapping material coming together. A strapping tool or strapping machine connects these ends after the correct tension has been applied. A strapping tool or strapping machine closes the strapping band using a seal or buckle, or by welding the ends together. After this, the excess strapping band is cut automatically. All materials, sizes and shapes can be strapped. Applications of strapping Examples of concrete applications of strapping are: Closing boxes and shipping containers Bundling for handling and shipping: e.g., newspapers, pipes, wood or concrete blocks Attaching or securing products to pallets and crates Reinforce wooden boxes, cardboard boxes and crates Attach items to flat wagons or flatbed trailers Securing a unit load such as bricks or flat glass Keep rolls of steel or paper together Lifting assistance with for example roof tiles or newspapers Theft protection: it can be seen immediately if the strapping band has been removed Why a Reliable Strapping System Is a Key Part of Successful Automatic Systems In today’s manufacturing facilities, typically half of production hours rely on the use of manual or physical labor. Reducing your dependency on manual work through automation has the potential to increase your revenue and efficiency. It speeds up repetitive tasks and allows your workers to focus on other things. If you want to optimize your use of equipment, consider which processes are most apt for automation. Your machines should speed up labor-intensive processes without high maintenance and energy costs. Investing in a high-quality strapping system is one of the best automation decisions you can make because it offers many benefits. Here are seven ways steel stacking and strapping machine line will improve your efficient: 1. Greater Efficiency There are many reasons to automate your equipment — from decreasing labor costs to reducing human error. A reliable strapping system for your manufacturing plant can resolve these inefficiencies while also boosting performance in critical areas. Energy Efficiency A reliable strapping machine can improve energy efficiency by eliminating heat from the sealing process. EAM-Mosca Corporation’s ultrasonic sealers do not use continuous heat. Instead, our innovative solution utilizes ultrasonic waves to produce a molecular level seal in the strap. As a result, the machine only requires energy when the seal forms, greatly reducing the energy consumed in the sealing process. Material Efficiency Using an automated strapping system, your facility will use less banding material. When employees strap packages or bundles by hand, they tend to overestimate the strap length. If you band containers of varying sizes, it is harder to gauge the amount of strap needed consistently. An automated strapping system will self-calibrate for any bundle dimensions and cut and seal the exact amount of strap needed. Plus, it can make this estimation in a split second, much faster than manual banding. As a result, you’ll experience less material waste and a faster process. The technology can further improve material efficiency because an ultrasonic seal is more consistent than a heat seal. Very often, you can select a narrower, or thinner and thus less expensive strap and get the same or better performance. It can seal both Polypropylene (PP) and Polyester (PET) bands and switch between them with minor adjustments to use the most efficient material for any bundle or load. We’ve saved some of our customers 100 feet of strapping per coil when they switched to our sealing technology – footage that adds up to significant cost savings. 2. Improved Safety In general, automation has the power to keep the workplace safer by keeping workers away from dangerous processes. Since 2003, workplace safety incidents have gone from five per 100 full-time employees to around 2.8 in 2019, a figure that has held steady over several years. Many experts point to a correlation between a reduction in workplace injuries to an increase in automation. Manual strapping presents opportunities for safety hazards. Manual strapping requires a small team engaged in repetitive motions. An automated machine requires just one operator who can stay out of the banding mechanism’s direct line. By removing manual, repetitive motions, you can also create an ergonomically correct environment with fewer muscle-strains. This environment decreases fatigue, allowing your team to stay alert and less likely to get injured. The possibility of tripping hazards is greatly reduced with automatic equipment as well. The sealing technology can also improve safety over traditional automatic strapping systems. Unlike heat sealing systems, the ultrasonic system produces no smoke, fumes, or odors. 3. Lower Maintenance Costs The more reliable your automated equipment is, the less often it needs to be maintained. The longer you can stretch the service life of individual parts, the lower their lifetime cost. EAM-Mosca Corporation’s strapping machines reduce your maintenance costs with reliable equipment designed to reduce wear. Mosca’s strapping systems with sealing technology feature wear-free DC brushless direct drives. Many of the components are designed to create less wear, such as its sealed bearings, which block dust and debris. And ultrasonic sealing creates no residues like heat-sealing does, which also reduces maintenance. The result of all these innovations is an efficient machine that can run longer with fewer repairs. Another area that contributes to your maintenance costs is the loss of productivity during upkeep or failures. While prolonging the time between repairs helps to lessen these costs, we take things even further. Our system can be disassembled without the use of tools and a head replacement takes only 30 seconds. We also make it easy to change out the strap coil. The machine senses the empty coil and ejects any leftover strap from the feed. The equipment is then ready for a new coil to be loaded, saving time and material. We were able to reduce one of our client’s coil change time from four minutes to two minutes when we installed machines. With fast, user-friendly maintenance features, your plant can get back to production in record time. 4. Enhanced Productivity An efficient, automated system improves your plant’s productivity in many vital ways. By using equipment that can do rote tasks faster and more affordably, your team can focus on more skill-intensive tasks. That benefit is undoubtedly the case for automatic strapping machines, which have the functionality to band up to 50 items per minute, depending on the application. Manual strapping requires a small team to keep pace with your production lines. An automatic strapping machine needs just one worker to feed packages or bundles for banding. You can even combine it with a conveyor belt system, which can strap items one after the next at a faster rate. Choose from strapping system conveyors and turners built for high volume or adjustable speeds. With so much of the strapping process happening by machine, your workers are freed up for other jobs. What you do with that extra labor can further enhance your productivity. Use that spare time to upskill your workers to form an elite team. Or, move them to delicate aspects of the process that still require a personal touch and critical thinking. When your workers get to focus on more diverse tasks, they are more engaged and productive in their work. You also get the benefit of putting talented workers where they’ll be most effective. With fewer repetitive tasks, they’ll be less fatigued, less likely to get hurt, and more effective. Another benefit of our technology is that it can handle varying strapping tensile strengths and load sizes. Some bundles, such as soft cloth or thin stacks of paper, need a looser band to prevent damage to the machine product. Others, like heavy pallets and boxes ready for shipping, need a tighter, heavier duty strap to keep items in place. The system can handle all these jobs on the same machine. All you have to do is set the tension required. Furthermore, many facilities need reliable strapping for different sized packages. Our strapping systems self-calibrates to the size of the bundle or load passing through. By tracking the parameters, it automatically cuts the amount of strap needed to secure it. You can send items of varying sizes through the conveyor without having to adjust the settings.
