Embodiment Construction

[0024] 1. In the production process of soy sauce and vinegar, bottled and bagged soy sauce and vinegar need to be sterilized before packaging. The soy sauce or vinegar that needs to be sterilized in the storage tank (1) is pressed into the heating tube (5) by the hydraulic pump (2), and is heated and sterilized by the microwave heating chamber (6). The sterilization temperature and sterilization time are determined by Microwave heating power, temperature measuring and controlling instrument and hydraulic pressure and liquid material flow speed adjustment control, the sterilized material is cooled rapidly by the cooler (7), the whole cooling process can be carried out in stages, and part of the cooling medium can be liquid material that needs to be heated and sterilized , so that the liquid material to be sterilized can be preheated during the cooling process, and the sterilized material can be cooled to reduce energy loss. Sterilized liquid materials are packaged aseptically. ...

Abstract

The invention relates to a microwave heating pipe manufactured by a composite pipe which manufactures an external wall by using polyfluortetraethylene and manufactures a lining by using makrolan or polypropylene materials, and the heating pipe has a high permeation ratio to microwaves, and can endure the sterilizing temperature of 120 to 140 DEG C and the hydraulic pressure environment of 0.199Mpa to 0.5MPa for a long time. The composite pipe can be used for the heating and sterilizing treatments of liquid foods and medicaments in microwave fields, and no toxic substances can be produced in the treating process, thus satisfying the heating and quick sterilizing requirements and hygienic safety requirements of liquid materials, such as foods, medicaments and the like. The method can be applied in various technical fields of foods, pharmacy, fermentation, treatments of organism waste, chemical engineering and the like.

Description

[0001] 1. Involved technical fields [0002] "A method and equipment for microwave heating and sterilization of liquid materials" involves the fields of bioengineering, chemical engineering, food and environmental engineering. 2. Background technology [0003] Microwave refers to electromagnetic waves with a frequency in the range of 300MHz to 300GHz. It was first used in military radar and communication fields. Later, people discovered that using microwaves to irradiate objects will produce thermal effects, causing the temperature of the irradiated objects to rise rapidly. This characteristic of microwave has been widely used in food and medicine industries, and a large number of households have entered the family. Microwave generators and corresponding control technologies have been relatively mature and perfect. There are two types of fixed dedicated microwave frequencies for industrial and daily use equipment. That is 915MHz and 2450MHz; recent scientific research shows th...
