Soilless and carbon-free filtration system for high fructose corn syrup

Abstract

The invention relates to the technical field of light industry and chemical engineering biotechnology, in particular to a high fructose corn syrup soilless carbon-free filtering system which comprises a fructose saccharifying tank, and the upper end of the fructose saccharifying tank is a syrup input end and used for being connected with a syrup input structure; a first clarified liquid outlet is formed in the middle of the fructose saccharifying tank and connected with the input end of the membrane filtration equipment, a first residue liquid outlet is formed in the lower end face of the fructose saccharifying tank and connected with the input end of the plate-and-frame filter, and the output end of the plate-and-frame filter is connected with the input end of the clarified liquid tank. A second clarified liquid outlet and a second residue liquid outlet are respectively formed in the middle part and the lower end surface of the clarified liquid tank and are respectively connected with the input end of the membrane filtration equipment and the input end of the plate-and-frame filter; and the membrane filtration equipment is provided with a filtration liquid output port for outputting filtration liquid. The filter has the advantages that the cost can be better saved, impurities can be better filtered and removed to improve the filtering quality, and the filter residue quality can be better improved to enable the value of filter residue accessory products to be higher.

Description

technical field [0001] The invention relates to the technical fields of light industry and chemical industry biotechnology, in particular to a soilless and carbon-free filtration system for fructose syrup. Background technique [0002] Fructose syrup is a starch syrup made by hydrolysis and isomerization of plant starch, and is an important sweetener. The production of fructose syrup is not restricted by region and season, the equipment is relatively simple, and the investment cost is low. Because its composition is mainly fructose and glucose; it is called "fructose syrup". Colorless viscous liquid, good fluidity at room temperature, odorless. Fructose syrup is mainly composed of glucose and fructose. According to fructose content, fructose syrup is divided into three national standards: fructose syrup (F42 type) contains fructose 42%; fructose syrup (F55 type) contains fructose 55%; fructose syrup (F90 type) contains fructose 90%. The sweetness of fructose syrup is pos...

Problems solved by technology

[0003] In the traditional fructose syrup filtration system, it is necessary to use a large amount of filter aids (activated carbon and perlite) to assist in filtering out impurities in the sugar solution. This process is highly resistant to filter aids, the amount of aids used is large, and the cost of auxiliary materials is high

In addition, the filter aids have the risk of penetrating the filter layer and causing sugar liquid pollution.

At the same time, impurities such as oil and protein in the sugar solution cannot be removed, which affects product quality

Due to the addition of filter aids, activated carbon and other substances in the sugar solution, when these substances are pressed by the filter machine, the formation of the filter cake will not be good enough, which will affect the selling price of the filter residue.
