Abstract

The invention discloses a sterilizing method for jam and fruit juice which are heated directly by steam and cooled by flash evaporation, which comprises the following steps of: 1) mixing jam or fruit juice raw materials and the steam, and heating quickly to the sterilizing temperature to obtain high-temperature materials; 2) keeping the temperature and sterilizing the materials obtained in the step 1); and 3) cooling the materials obtained in the step 2) quickly by a flash evaporation process. The invention also aims to provide a sterilizing device for the jam and the fruit juice, which comprises a steam injection heater, a maintaining tank and flash evaporation equipment which are connected sequentially, wherein the flash evaporation equipment comprises a flash evaporation cooler connected with the maintaining tank and a vacuum pump connected with the flash evaporation cooler. By the sterilizing method and the sterilizing device for the jam and the fruit juice which are heated directly by the steam and cooled by the flash evaporation, the pasteurization of the jam and the fruit juice can be realized, the concentration and viscosity of products can be improved, the color and luster of the products can be protected, so that the high-quality jam and fruit juice products are obtained, and the products can be widely used.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method and device for sterilizing jam and fruit juice through direct steam heating and flash cooling. Background technique [0002] In the production process of jam and juice products, killing the active enzymes and microorganisms in the products is a necessary production process. By heating, the microorganisms and active enzymes in the product are killed to ensure that the product is not corrupted for a long time, which is defined as product sterilization or pasteurization. [0003] In the traditional sterilization process, partition heating and cooling are usually used. In the ketchup industry, sleeve heaters, holding tubes and coolers are commonly used in sterilizers. Adopt this sterilizing process and sterilizing machine to have following shortcoming: [0004] First, the traditional sterilization process takes 12 to 15 minutes from the initial heating of the product to the...
