Problems solved by technology

Take a newly built starch sugar company in Chongqing as an example. In the off-season, the ten-day or monthly production capacity of the 200,000 / year equipment line has more than doubled the market demand at that time, but in the summer 1 ~ During the best-selling period of fructose syrup products in February, at least 300,000 / year production capacity (over 100 million investment) has to be added to meet the immediate demand of the market

Abstract

The invention discloses a method for quality guaranteeing and storage of fructose corn syrup products. The method includes the steps: fructose corn syrup from a multi-effect concentrator on a production line is cooled, vacuum degassing is conducted, and degassed fructose corn syrup is obtained; nitrogen is filled into the degassed fructose corn syrup, and nitrogen-filling treatment is conducted; astorage tank is vacuumized, the fructose corn syrup subjected to nitrogen-filling treatment is pumped into the storage tank, and nitrogen is filled into the top of the storage tank; all ventilating openings of the storage tank are closed, and a bypass valve of the storage tank is opened, so that an oxygen absorbent and a water absorbent communicate with gas on the upper part of the storage tank,and the oxygen concentration is controlled to enable the fructose corn syrup to enter into a storage state; and the temperature of the fructose corn syrup entering into the storage state, the intensity of pressure of the gas on the upper part of the storage tank and the concentration of the gas on the upper part of the storage tank are detected, by filling or pumping out the stored gas, the gas concentration is controlled, and thus the fructose corn syrup is subjected to quality guaranteeing and storage for 90-150 days. According to the method provided by the invention, the shelf life of the fructose corn syrup products can be prolonged, and the method has positive significance for balanced production of the fructose corn syrup in one year.

Description

technical field [0001] The invention belongs to the field of fructose syrup production, and in particular relates to a quality preservation and storage method for fructose syrup products. Background technique [0002] High fructose syrup is also called high fructose syrup, and its main components are fructose and glucose. According to the amount of fructose, it is divided into several categories such as F-42, F-55 and F-90. Generally, refined corn starch is used as raw material, and after multi-enzyme method for liquefaction, saccharification, decolorization, ion exchange, and isomerization, a mixture of fructose and glucose is obtained, and then F-42 is obtained by decolorization, ion exchange, evaporation and concentration, and then used F-90 can be obtained by chromatographic separation on a simulated moving bed, and F-55 can be obtained by mixing the two, and its sweetness is equivalent to that of sucrose. Fructose syrup is relatively cheap and has excellent properties ...
