Description

一种实验型微波杀菌装置和杀菌方法An experimental microwave sterilization device and sterilization method

技术领域technical field

本发明属于流体食品药品生产研发技术领域,尤其涉及一种实验型微波杀菌装置和杀菌方法。The invention belongs to the technical field of fluid food and drug production research and development, in particular to an experimental microwave sterilization device and a sterilization method.

背景技术Background technique

流体食品药品在灌装前,通常需要对其进行杀菌处理。现有的方法是采用高温瞬时杀菌、巴氏杀菌等来处理流体。该方法中,流体保持高温的时间相对较长,且流体承受的温度也相对较高。会对流体中的热敏性成分造成较大的损失,影响产品的风味及胶体界面特性。Liquid food and medicine usually need to be sterilized before being filled. The existing method is to use high temperature flash sterilization, pasteurization, etc. to treat the fluid. In this method, the fluid is kept at a high temperature for a relatively long time, and the temperature the fluid is subjected to is relatively high. It will cause a large loss of heat-sensitive components in the fluid, affecting the flavor and colloid interface characteristics of the product.

对于常用的巴氏杀菌,比如巴杀液蛋,现在普遍的杀菌装置,基本都采用蛋液与热水之间进行热传导的方式来进行杀菌。对蛋液进行巴氏杀菌的热水,需要在3个大气压下被加热到135℃,才能达到有效的杀菌效果。并且加热效果不均匀,保证中心蛋液充分灭菌时,外周蛋液的品质下降,因此常常难以达到完全加热杀菌的目的。加热完毕的热水又需要重新加热才能进行重新使用。大量热水的使用,既浪费了资源,又容易造成意外。For commonly used pasteurization, such as liquid pasteurized eggs, the current common sterilization devices basically use heat conduction between egg liquid and hot water for sterilization. The hot water for pasteurizing egg liquid needs to be heated to 135°C under 3 atmospheres to achieve effective sterilization effect. In addition, the heating effect is uneven, and when the central egg liquid is fully sterilized, the quality of the peripheral egg liquid decreases, so it is often difficult to achieve the purpose of complete heating and sterilization. The heated hot water needs to be reheated before it can be reused. The use of a large amount of hot water not only wastes resources, but also easily causes accidents.

对于流体常用的超高温瞬时灭菌,现有的设备同样具有上述巴氏杀菌缺陷,同时因设备制造利用热传导原理,难以实现小型化,目前实验型设备最小需要的样品量也约4-5L,这对于实验室研发而言,尤其是流体组成含有高价值组分或尚难于大批量商业化的组分而言,几乎是难以逾越的瓶颈,致使很多流体食品、药品的商业开发或实验样品制备在该灭菌环节卡壳。For the commonly used ultra-high temperature instantaneous sterilization of fluids, the existing equipment also has the above-mentioned pasteurization defects. At the same time, it is difficult to achieve miniaturization due to the principle of heat conduction in equipment manufacturing. At present, the minimum sample volume required for experimental equipment is about 4-5L. This is an almost insurmountable bottleneck for laboratory research and development, especially for the components whose fluid composition contains high-value components or is difficult to commercialize in large quantities, resulting in the commercial development of many fluid foods, pharmaceuticals or experimental sample preparation. Stuck in this sterilization link.
