Solution freeze-concentration device and efficient concentration process thereof

Abstract

The invention relates to the technical field of freeze concentration of solutions. The invention relates to a solution freeze-concentration device and an efficient concentration process. The device comprises a tank body, a refrigerating device, a separating device and a deicing device, wherein the refrigerating device is arranged at the top end of the inner side of the tank body; the top end of the right end surface of the tank body communicates with a feeding pipe; an electric control valve is fixedly connected to the feeding pipe; the bottom end of the right end surface of the tank body is fixedly connected with a controller; and a fixed box is fixedly connected to the bottom end of the outer side of the tank body. According to the invention, through cooperation among the arrangement aninner pipe and a sleeve, the communication of the inner pipe and a partition plate, the communication of the sleeve and a refrigerant box and the fixed connection of the partition plate and the refrigerant box, the efficiency of cooling an extraction liquid is improved when the extraction liquid is concentrated according to the requirements that a solid concentration is 10% and a final solid concentration is 26% by means of the freezing concentration mode that a refrigerant is injected into the refrigerant box through a liquid inlet pipe, and therefore, the production demands of products can be met to the maximum extent, product quality is guaranteed, an additional value is increased, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of solution freeze concentration, in particular to a solution freeze concentration device and a high-efficiency concentration process thereof. Background technique [0002] At present, the processing process of instant coffee powder at home and abroad is pretreatment section, extraction (concentration 5% ~ 12%) section, aroma enhancement section, heat concentration (concentration 42% ~ 55%) section, blending section, spray drying section or freeze drying In the process section, because the hot concentration destroys the heat-sensitive substances such as the flavor, aroma and nutritional components of the coffee, the extracted coffee liquid is first distilled out part of the aroma liquid through the aromatherapy equipment before the heat concentration, and then the heat concentration is carried out, and the aroma liquid is restored after the heat concentration Returning to the coffee concentrate is the deploy...

AI Technical Summary

Problems solved by technology

[0003] In the field of freeze concentration of coffee solution, the traditional hot concentration method has seriously affected the quality of the product, reduced the added value of the product, wasted energy and water resources, although there are some freeze concentration methods, but because the coffee material is easy to be Entrainment in ice cubes will cause high material loss, which increases the cost of investment. In addition, some freeze-concentration methods cannot automatically discharge ice cubes, which greatly reduces the scope of application of the device. In the way of concentration, the cooling efficiency is low during freeze concentration, which cannot meet the production needs to the greatest extent. Therefore, a solution freeze concentration device and its high-efficiency concentration process are proposed to solve the above problems.
