氣調(diào)式冷庫(kù)
氣調(diào)冷庫(kù)是在冷藏庫(kù)的基礎(chǔ)上增加氣體成分調(diào)節(jié)，通過(guò)對(duì)貯藏環(huán)境中溫度、濕度、二氧化碳、氧氣濃度和乙烯濃度等條件的控制，抑制果蔬呼吸作用和自我消耗，使之處于近休眠狀態(tài)減少失水減少病害發(fā)生，延緩其新陳代謝過(guò)程，從而較長(zhǎng)間的保持被儲(chǔ)物的質(zhì)地、色澤口感、營(yíng)養(yǎng)等基本不變，更好地保持果蔬新鮮度，達(dá)到延長(zhǎng)果蔬貯藏期的目的，是目前國(guó)際上使用普遍、先進(jìn)的貯藏保鮮技術(shù)之一。
The air-conditioning cold storage is based on the increase of gas composition in the cold storage. By controlling the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, the respiration and self-consumption of fruits and vegetables are reduced to reduce the water loss. Reducing the occurrence of diseases and delaying its metabolic process, so as to maintain the texture, color, taste and nutrition of the storage materials for a long period of time, to maintain the freshness of fruits and vegetables, and to extend the storage period of fruits and vegetables, the most common use in the world is currently the best. One of the most advanced storage and preservation technologies
氣調(diào)庫(kù)儲(chǔ)藏的原理
傳統(tǒng)的果蔬貯藏保鮮方法有簡(jiǎn)易貯藏、通風(fēng)庫(kù)貯藏、輻射保鮮、化學(xué)保解、冷庫(kù)保鮮、簡(jiǎn)易貯藏、通風(fēng)庫(kù)貯藏，設(shè)備簡(jiǎn)單投資少但貯藏效果差，貯藏期短腐爛損失嚴(yán)重，輻射及化學(xué)保鮮在部分水果上有一定適用性，但存在輻射及化學(xué)殘留污染，不是所有果疏都能應(yīng)用，氣調(diào)貯藏能在適當(dāng)?shù)蜏貤l件下通過(guò)改變貯藏環(huán)境氣體成分，相對(duì)溫度極大程度地創(chuàng)造果蔬貯藏良好環(huán)境，其效果表現(xiàn)在以下方面，氣調(diào)貯藏營(yíng)造的低氧（一般02含量為1％-5％，適當(dāng)?shù)腃O2濃度能有效地抑制呼吸作用，減果蔬中營(yíng)養(yǎng)物質(zhì)的損耗，同時(shí)抑制病原菌的滋生繁殖，控制某些生理病害的發(fā)生，清除貯藏環(huán)境氣體中的乙烯以抑制其對(duì)果蔬的催熟作用，延緩后熟和衰過(guò)程，增加環(huán)境氣體中的相對(duì)濕度以降低果蔬的蒸騰作用從而達(dá)到果蔬長(zhǎng)期貯藏保鮮的目的）
The traditional method of storage and preservation of fruits and vegetables has simple storage, ventilation storage, radiation preservation, chemical preservation, cold storage, fresh storage, simple storage, ventilation storage, simple storage, low storage, but poor storage. Short storage time, short decay, severe radiation and chemical preservation. Sexual but there are radiation and chemical residual pollution. Not all the fruits can be used. The modified atmosphere can be used to create the optimal environment for the storage of fruits and vegetables by changing the relative temperature of the gas components under the appropriate low temperature conditions. The effect is as follows: Hypoxia (usually 02 content of 1% 5%) The appropriate CO2 concentration can effectively inhibit the respiration and reduce the loss of nutrients in fruits and vegetables while inhibiting the growth and reproduction of pathogenic bacteria to control the occurrence of certain physiological diseases. In order to inhibit the ripening effect of fruits and vegetables, the relative humidity in the ambient gas is increased to reduce the transpiration of fruits and vegetables, thereby achieving the purpose of long-term storage and preservation of fruits and vegetables.

After the barrel pump unit is used, the gas return to the gas in the barrel is realized, and the working medium entering the compressor is realized as a dry gas to avoid the possibility of the compressor running on the wet stroke.
The use of a fluorine pump to force the liquid supply method to multiply the full liquid supply due to the increase in the flow rate of the liquid supply in the evaporator, so that the cooling efficiency of the evaporator is improved, thereby improving the heat exchange effect of the through-type equipment. The heat exchange (gas superheated liquid is too cold) has achieved the effect of double bottom, which effectively solves the oil return problem of the compressor fluorine system.
The barrel pump unit is equipped with an automatic manual oil return system in the heat exchanger of the oil university and returns to the compressor to effectively solve the oil return problem of the compressor fluorine system and improve the reliability of the system operation.
