Description
技术领域technical field
本实用新型涉及水果蔬菜、熟食、生鲜肉类等食品保鲜的家用电器。The utility model relates to a household appliance for fresh-keeping food such as fruits and vegetables, cooked food and fresh meat.
背景技术Background technique
我们家庭日常食用的水果蔬菜、熟食、生鲜肉类等食品的保鲜，都是采用家用电冰箱进行保鲜。家用电冰箱一般都是采用制冷压缩机降温进行保鲜，对水果蔬菜、熟食、生鲜肉类等食品的保鲜效果不好，几天内就会败坏变质，电冰箱的冷冻保鲜仅适用于生鲜肉类等可以冷冻的食品，不适用于水果蔬菜、熟食的保鲜，因此家用电冰箱的使用，有很大的局限性。Household refrigerators are used to keep fresh fruits and vegetables, cooked food, fresh meat and other foods that our family eats daily. Household refrigerators generally use refrigeration compressors to cool down for freshness preservation. The preservation effect on fruits and vegetables, cooked food, fresh meat and other foods is not good, and they will deteriorate within a few days. The freezing preservation of refrigerators is only suitable for raw Foods that can be frozen, such as fresh meat, are not suitable for the preservation of fruits, vegetables, and cooked food. Therefore, the use of household refrigerators has great limitations.
发明内容Contents of the invention
水果蔬菜的保鲜需要储存箱内温度、湿度、负压、氧气含量、灭菌条件综合技术的调节，才能达到好的保鲜效果。熟食、生鲜肉类食品的保鲜需要储存箱内温度、负压、氧气含量、灭菌条件综合技术的调节，才能达到好的保鲜效果。The preservation of fruits and vegetables requires the adjustment of temperature, humidity, negative pressure, oxygen content, and sterilization conditions in the storage box to achieve a good preservation effect. The preservation of cooked food and fresh meat requires the adjustment of the temperature, negative pressure, oxygen content, and sterilization conditions in the storage box to achieve a good preservation effect.
本实用新型的目的是提供了一种采用制冷压缩机制冷降温、真空减压调理气体含量、臭氧灭菌、加湿保鲜的新的技术方案的食品真空调理气调保鲜柜。The purpose of this utility model is to provide a food vacuum air-conditioning air-conditioning fresh-keeping cabinet which adopts a new technical scheme of refrigeration compressor refrigeration and cooling, vacuum decompression to adjust gas content, ozone sterilization, humidification and fresh-keeping.
为了实现本实用新型的目的，这种食品真空调理气调保鲜柜包括食品储存箱、制冷压缩机、真空泵、超声波加湿器、臭氧灭菌发生器。In order to realize the purpose of the present utility model, this food vacuum-conditioning air-conditioning fresh-keeping cabinet comprises a food storage box, a refrigeration compressor, a vacuum pump, an ultrasonic humidifier, and an ozone sterilizing generator.
为了便于不同类食品之间保鲜参数的调节控制，防止食品之间串味，本真空调理气调保鲜柜的食品储存箱分为水果蔬菜保鲜区、熟食保鲜区、生鲜肉类保鲜区，三个分别独立密闭的储存箱，利于调节各自的保鲜参数。In order to facilitate the adjustment and control of fresh-keeping parameters between different types of food, and prevent food from cross-flavoring, the food storage boxes of this vacuum-conditioned atmosphere fresh-keeping cabinet are divided into three areas: fruit and vegetable fresh-keeping areas, cooked food fresh-keeping areas, and fresh meat fresh-keeping areas. The independent and airtight storage boxes are convenient for adjusting their fresh-keeping parameters.
本实用新型的工作原理是：采用了制冷压缩机对食品储存箱进行降温。采用了真空泵对食品储存箱进行真空减压，通过食品表面水分的蒸发，带走食品内部的热量；真空减压的同时也降低了储存箱内氧气的含量，减少了食品的氧化变质和细菌微生物的滋生。采用了超声波加湿器对水进行雾化的原理，来对水果蔬菜保鲜区储存箱内增加湿度，利于水果蔬菜的保水保鲜。采用了臭氧发生器产生臭氧，利用臭氧的强氧化特性，来对食品储存箱不定时的释放臭氧，进行杀菌防腐。The working principle of the utility model is: a refrigeration compressor is used to cool down the food storage box. The vacuum pump is used to decompress the food storage box, and the heat inside the food is taken away through the evaporation of moisture on the surface of the food; the vacuum decompression also reduces the oxygen content in the storage box, reducing the oxidative deterioration of food and bacterial microorganisms breeding. The principle of atomizing water by an ultrasonic humidifier is used to increase the humidity in the storage box in the fresh-keeping area of fruits and vegetables, which is conducive to water retention and freshness of fruits and vegetables. An ozone generator is used to generate ozone, and the strong oxidation characteristics of ozone are used to release ozone from time to time for food storage boxes for sterilization and antisepsis.
使用时，制冷压缩机通过安装于储存箱外的冷凝器和安装于储存箱内的蒸发器组成闭环回路，对储存箱进行降温；真空泵由一条管路连接到各个食品储存区，利用电磁阀切换对各个食品储存区进行真空减压，降低氧气含量；超生波加湿器仅安装在水果蔬菜保鲜区内，来保持水果蔬菜保鲜区的合理湿度；臭氧发生器由一条管路连接到各个食品储存区，利用电磁阀切换对各个食品储存区进行释放臭氧，灭菌防腐。When in use, the refrigeration compressor forms a closed-loop circuit through the condenser installed outside the storage box and the evaporator installed in the storage box to cool down the storage box; the vacuum pump is connected to each food storage area by a pipeline, and is switched by a solenoid valve Carry out vacuum decompression in each food storage area to reduce the oxygen content; the ultrasonic humidifier is only installed in the fruit and vegetable fresh-keeping area to maintain a reasonable humidity in the fruit and vegetable fresh-keeping area; the ozone generator is connected to each food storage area by a pipeline , use the electromagnetic valve to switch to release ozone in each food storage area, sterilize and prevent corrosion.
有益效果Beneficial effect
本实用新型采用上述方案后，是对储存食品的真空压力、温度、湿度、氧气含量、灭菌条件的综合调理调节保鲜，更符合食品保鲜的基理，食品的保鲜保质期大大延长。与家用电冰箱相比，食品的保鲜期延长10倍以上。After the utility model adopts the above-mentioned scheme, it is a comprehensive adjustment and preservation of the vacuum pressure, temperature, humidity, oxygen content and sterilization conditions of the stored food, which is more in line with the basic principle of food preservation, and the freshness and shelf life of the food is greatly extended. Compared with household refrigerators, the preservation period of food is extended by more than 10 times.
