摘要
针对肉食品专营店和餐饮店对冷冻肉的解冻需求,设计研制了一台新型高压静电解冻柜。该解冻柜采用了高压静电解冻技术。设计了基于可编程逻辑控制器(PLC)的控制系统,可自动调控解冻柜温湿度和电场强度。根据设计性能参数,计算了解冻过程所需加热、制冷负荷和加湿蒸汽量。经解冻实验表明,该解冻柜能缩短解冻时间,降低汁液流失率,抑制微生物的繁殖,且解冻后肉样外观新鲜,肉色泽鲜红,具有实际应用价值。
Aiming at the requirements of meat shops and restaurants to thaw frozen meat, a new high voltage electrostatic thawing machine was designed. The thawing machine adopted high voltage electrostatic thawing technology. Control system based on programmable logic controller （PLC） was designed, which could control the temperature humidity and electric field intensity automatically. According to the performance parameters of design, the thawing process need for heat load, cool load and wet steam were calculated. Thaw experiment showed that the thawing machine could decrease thawing time and juices loss, inhibit the growth of bacteria. The appearance of meet was fresh, color and luster was bright red, it did have practical application value.
