Embodiment example

[0038] Case 1:

[0039] In this example, abalone viscera polysaccharide solution with a concentration of 1% is used as the raw material concentration to calculate the concentration of soluble solids, and the suspension type freeze concentration treatment is carried out. The specific steps are as follows:

[0040] (1) the abalone viscera polysaccharide solution with a concentration of 1% is placed in the recrystallization tank 5 earlier, and the liquid level in the recrystallization tank 5 is slightly lower than that in the ice discharge tank 7, close the valve 14, and open the pump a , start the material circulation system, pump the liquid into the liquid distribution plate 2, the distribution plate rotates under the drive of the reducer, the liquid flows out from the small hole in the plate wall and is thrown to the inner surface of the scraper heat exchanger 1 to flow down the wall and carry out Heat exchange, set its temperature to -20°C.

[0041] (2) Start the ice scrapin...

Abstract

The invention belongs to the field of processing, and specifically relates to novel suspension type freeze concentration equipment. The novel suspension type freeze concentration equipment provided by the invention comprises a scraper type heat exchanger, a liquid distribution disc, an ice scraping device, an ice crystal carrying tank, a heavy crystallizing tank, an ice crystal delivery pipe, an ice discharging tank and a material supplying tank, wherein the lower end of the scraper type heat exchanger is connected with the upper end of the ice crystal carrying tank, and the lower end of the ice crystal carrying tank is connected with the upper end of the heavy crystallizing tank; the upper part of the heavy crystallizing tank is communicated with the ice discharging tank through a guiding pipe, the bottom or side surface of the heavy crystallizing tank is communicated with one end of a pipeline I with a pump a, and the other end of the pipeline I is connected with the top of the scraper type heat exchanger so as to form a material liquid circulating system. The novel suspension type freeze concentration equipment provided by the invention has the characteristics that the energy consumption is low, a scraper is not easy to clamp, the concentration efficiency is high, the operation is simple, few controlling conditions are required, and the production efficiency is high, and thus the novel suspension type freeze concentration equipment is beneficial for mass production application.

Description

technical field [0001] The invention belongs to the field of processing, and in particular relates to a novel suspension freeze concentration equipment. Background technique [0002] In the food industry and pharmaceutical industry, especially in the field of processing liquid materials, concentration has gradually become an indispensable unit operation in the process. Concentration can not only remove a large amount of water in the material, increase its concentration, reduce its water activity, and prolong the shelf life of the product; it can also be used as a pretreatment process for crystallization, drying and other processes. At present, there are three methods of concentration: evaporative concentration, membrane concentration, and freeze concentration. Evaporation and concentration is to utilize the difference in volatility between the solute and the solvent in the liquid material, and use heating to vaporize and remove part of the solvent in the material, and separ...
