Silicon Window Gas Storage Storage Garlic Technology
In the early 1980s, China began to promote the air-conditioning technology of silicon windows to keep fresh garlic sprouts. It is through the inlaying of a certain area of ​​silicone rubber film on the plastic bag to automatically adjust the gas composition in the bag to achieve the purpose of preservation. It has the advantages of labor saving, time saving, energy saving, convenient management, stable gas composition, long storage period, low loss, and quality. Good features. The economic benefits are significant, so they are widely used in a short period of time. First, the silicon window gas storage store garlic bulb 1. Silicon window use form Cold storage Silicon window air conditioner has a small package plastic bag and plastic account two forms. In general, cold storage bags are often used in small packages, which are easy to use and can be sold as bags to reduce costs. The small packaging bag is made of 0.08 mm thick polyethylene film and a certain area of ​​silicone rubber film, which is made by heat sealing with a high-frequency heat sealing machine. It has specifications of 15 kg, 20 kg, 25 kg and so on. 2. Silicon window area plan General silicone rubber film manufacturers will provide a ton of garlic sprouts applicable area. When used, it can be folded in proportion. For example, the FC-8 membrane produced by Lanzhou Biochemistry Co., Ltd. is used for garlic bulbs 0.4 square meters/ton to 0.5 square meters/ton. 3. Advantages of fresh air-sealing and fresh-keeping of garlic-silicon windows: low loss, long storage period, good quality, and significant economic benefits. Due to the self-adjusting function of the silicon window, the gas composition in the entire storage bag is basically stabilized at a more desirable level, which can not only avoid carbon dioxide poisoning, but also prevent the quality from aging, and at the same time inhibit bacterial growth and reduce decay. In general, the gas window of the silicon window is better than the plastic bag deflating method, the production rate is 5% to 15% higher, the dry energy consumption is 2% lower, the decay rate is reduced by more than 5%, and the selling price is much higher than the latter. 2 Convenient management, saving time and energy, and saving energy. The silicon window storage bag is basically the same as the deflation method in management, but it saves more than 20 operations such as deflation, sorting, and water cleaning, which can save 80% of labor, and at the same time reduce the energy consumption and bag loss during operation. Phenomenon, reducing costs and ensuring quality. Second, the control of the gastrogen storage of garlic pest disease 1. Cold temperature can reduce the temperature of the fruit and vegetable respiratory metabolism, delay tissue aging, inhibit microbial reproduction, reduce decay, extend the storage period. However, if the temperature is too low, low temperature disease will occur. The optimum temperature for storage of garlic sprouts is 0°C, and the minimum temperature must not be lower than -1°C. When the temperature is lower than -1°C for a short time, garlic sprouts can be recovered. If the cell membrane is damaged, it can not be recovered, resulting in freezing injury. The appearance is blisters, the tissue is translucent, the pigment is degraded, and it is boiled after thawing. , smelly. Storage temperature should be strictly controlled (0°C to -1°C) and helium temperature (0.5°C). 2. Carbon dioxide poisoning When the carbon dioxide gas in the bag is above 10% for a long time, it will cause carbon dioxide poisoning and cause the organism to suffocate. The performance is that the early stalks appear yellow spots, numb spots and gradually expand into round depressions, and the stalks are softened and broken. The pupa changes from green to gray and further develops. The stalks are water-stained and the epidermis is shed. The rot gives off a very strong taste of the wine. When using a silicon window for gas storage of garlic sprouts, be sure to choose a stable quality silicone rubber membrane, and strictly follow the instructions to configure the appropriate area of ​​silicon window, strictly according to the provisions of the weight of the bag; keep the temperature stable. And regularly detect the concentration of carbon dioxide in the bag and in the storehouse. 3. Microbial diseases The major microbial diseases during the storage period of garlic sprouts are microbial diseases such as tuber mildew, water rot disease, and helminthosis. In the atmosphere, the bag is kept under high humidity for a long period of time. The dried tip of the bag is easily rotted when it is put into storage, but generally it does not affect the bark. The horse worm is sick from Daejeon and the cause is unknown. When harvested, there are small yellow spots on the stems. If the timely storage after the acquisition, the gas composition is reasonable, the temperature of the reservoir is stable, and basically no disease or late onset, the harm is not great, otherwise it will cause great losses. Water rot is caused by mechanical damage caused by bacteria during loading, unloading and transportation. 4. Prevention and control measures for microbiological diseases 1 Ensure the quality of the acquisition, secure handling, selection, storage, pre-cooling, and timely bagging. 2 Ensure that the temperature is stable and reduce condensation. 3 drug fumigation: general use of clotrimidine (containing 50% sec-butylamine) 1.4g per cubic meter storage capacity. The fumigation option was performed before the gargle, avoiding the drug sticking directly to the garlic sprouts. Third, the silicon window of air-conditioned storage of garlic points Silicon window air-conditioned storage of garlic, the effect is good or bad, in addition to temperature and gas conditioning two necessary conditions, we must also pay attention to the quality of garlic, storage speed and warehouse management and other links. 1. Acquisition of garlic sprouts should ensure the quality of the quality of garlic storage is the basis for storage, the acquisition of garlic sprouts should be fresh, green, small. It is forbidden to purchase garlic pods that have been stored for a long time after aging, sickness or harvesting. If conditions permit, the factors such as planting, fertilizing, and irrigation should also be considered. 2. Timely delivery of imported garlic garlic in the importing warehouse is in the season of high temperature, rapid breathing and metabolism, rapid exotherm and aging, so the purchased garlic pods should be brought back to the cold storage in time, and the cold storage should be selected as soon as possible. 3. Pre-cooling, bagging on the shelf 1 cool down as soon as possible. During the early period of storage, garlic bulbs are hot, and the heat load is high. The operator of the equipment room must dilute the frost and ensure a good cooling effect. The temperature should be lowered in the shortest possible time. 2 When the temperature drops below 5%, it can be bagged. If the temperature is too high, it will cause too much water in the bag. When bagging, it must be weighed, with an error of no more than 10% per bag, and at the same time avoid puncturing the plastic bag. 3 After opening the bag, open the bag so that the temperature can be reduced to 0.5°C as soon as possible. At this point, wipe the water in the bag with a clean cloth, check the bag for damage, and then tie the bag. 4. Ensure stable storage temperature is the key to storage management In order to prevent low-temperature diseases, inhibit breathing, and reduce "sweat" garlic sprouts, we must ensure that the library temperature is stable. To this end, we must establish and improve a set of clear post responsibility system and a strict reward and punishment mechanism. At the same time to install an automatic temperature recorder to check the cooling situation. In addition, we regularly measure the composition of the gas and know what it is.
