气调式冷库

气调式冷库

气调冷库是在冷藏库的基础上增加气体成分调节通过对贮藏环境中温度、湿度、二氧化碳、氧气浓度和乙烯浓度等条件的控制抑制果蔬呼吸作用和自我消耗使之处于近休眠状态减少失水减少病害发生延缓其新陈代谢过程从而较长间的保持被储物的质地、色泽口感、营养等基本不变更好地保持果蔬新鲜度达到延长果蔬贮藏期的目的是目前国际上使用最普遍效最好、最先进的贮藏保鲜技术之一

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

气调库储藏的原理

传统的果蔬贮藏保鲜方法有简易贮藏、通风库贮藏辐射保鲜化学保解冷库保鲜简易贮藏通风库贮藏设备简单投资少但贮藏效果差贮藏期短腐烂损失严重辐射及化学保鲜在部分水果上有一定适用性但存在辐射及化学残留污染不是所有果疏都能应用气调贮藏能在适当低温条件下通过改变贮藏环境气体成分相对温度最大程度地创造果蔬贮藏最佳环境其效果表现在以下方面气调贮藏营造的低氧（一般02含量为1％5％适当的CO2浓度能有效地抑制呼吸作用减果蔬中营养物质的损耗同时抑制病原菌的滋生繁殖控制某些生理病害的发生清除贮藏环境气体中的乙烯以抑制其对果蔬的催熟作用延缓后熟和衰过程增加环境气体中的相对湿度以降低果蔬的蒸腾作用从而达到果蔬长期贮藏保鲜的目的

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.

The air conditioning library is generally composed of a pressure balance system of the air conditioning system air conditioning system refrigeration system humidification system and temperature and humidity, 02.Co2 gas automatic detection and control system

气调贮藏效果

抑制呼吸作用减少有机物质的消耗保持果蔬优良风味和芳香气味

抑制水分蒸发保持果蔬新鲜度

抑制病原菌的滋生繁殖控制某些生理病害的发生降低果实腐烂率

抑制某些后熟酶的活性抑制乙烯产生延缓后熟和衰老过程长期保持果实硬度有较长的储藏期

Inhibition of respiration reduces the consumption of organic matter and maintains the excellent flor and aroma of fruits and vegetables

Inhibit water evaporation to maintain freshness of fruits and vegetables

Inhibit the breeding of pathogenic bacteria, control the occurrence of certain physiological diseases, reduce the rate of fruit decay

Inhibition of certain post-mature enzyme activities inhibits ethylene production delays Post-ripening and senescence processes maintain long-term fruit firmness for a long shelf life

控制系统

要使气调库达到所要求的气体成分并保持相对稳定除了要有符合要求的气密性库体外还要有相应气体调节设备、管道、阀门所组成的系统即气调系统整个气调系统包括制氮系统、二氧化碳脱除系统乙烯脱除系统温度、湿度及气体成分自动检测

To make the air-conditioned storage reach theand maintain the relative stable， it is required to equip es apart from the airtight storage that meets with em，carbon dioxide deprivation system，ethylene defection and control system.

采用桶泵机组特点

采用桶泵机组后回气在桶中实现气液分离后使进入压缩机的工质实现为干燥气体避免了压缩机湿冲程运行的可能性

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 oid 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.
