Embodiment 1

[0056] On the starch liquefaction device provided by the present invention, it includes figure 1 and 2 The jet cooking equipment of the liquid replenisher shown is used to produce starch liquefaction liquid from high-concentration starch milk.

[0057] Among them, the inner diameter of the inlet of the liquid replacement device is 32mm, the outer diameter is 38mm (i.e. d2), the inner tube is expanded to an inner diameter of 42mm, and an outer diameter is 52mm (i.e. d1), and the cone angle γ of the enlarged diameter section is 42 °, the distance W is 30 mm; the outer tube is reduced in diameter through the reducing section, the outer diameter D1 is reduced from 76mm to D2 is 62mm, and the cone angle β of the reducing section is 42°. The minimum radial width of the radial gap formed between the inner tube and the outer tube is 0.4mm. The length L is 20 mm. The inner diameter of the liquid replenishing tube is 6mm, and it is arranged along the tangential direction of the outer...

Embodiment 2

[0065] According to the method of Example 1, the difference is that "30 L / h of soft water in the replenishment storage tank" is used instead of "30 L / h of sweet water in the replenishment storage tank".

[0066] Evaluate the liquefaction effect. The results are shown in Table 3.

[0067] table 3

[0068]

[0069] As can be seen from the results in Table 3, in Example 2, by adopting the method and equipment provided by the present invention, a small amount of hot soft water is tangentially injected into the radial gap of the liquid replenisher at a flow rate of 3% of the volume flow rate of the feed amount. When the dry starch content in the feed starch milk is as high as 45%, the starch milk jet cooking liquefaction system can still operate normally, and the filtration speed of the liquefaction liquid obtained after the system is still slightly faster than that of the comparative example. The filtration rate of the obtained liquefied liquid at 34% shows that the liquefied...

Embodiment 3

[0071] On the starch liquefaction device provided by the present invention, it includes figure 1 and 2 The jet cooking equipment of the liquid replenisher shown is used to produce starch liquefaction liquid from high-concentration starch milk.

[0072] Among them, the inner diameter of the inlet of the liquid replacement device is 32mm, the outer diameter is 38mm (i.e. d2), the inner tube is expanded to an inner diameter of 42mm, and an outer diameter is 52mm (i.e. d1), and the cone angle γ of the enlarged diameter section is 60 °, the distance W is 30 mm; the outer tube is reduced in diameter through the reducing section, the outer diameter D1 is reduced from 76mm to D2 is 63mm, and the cone angle β of the reducing section is 60°. The minimum radial width of the radial gap formed between the inner tube and the outer tube is 0.8mm. The length L is 20 mm. The inner diameter of the liquid replenishing tube is 6mm, and it is arranged along the tangential direction of the outer...

Abstract

The invention relates to the field of deep processing of starch, and discloses a fluid infusion machine, jet-cooking equipment, a starch liquefaction device, and a high-concentration starch milk jet-cooking and liquefying method. The fluid infusion machine comprises an outer pipe and an inner pipe which are in mutually sealed and sleeved connection and communication, wherein a fluid infusion machine inlet is formed in one end away from the outer pipe, of the inner pipe; a fluid infusion machine outlet is formed in one end away from the inner pipe, of the outer pipe; radial clearance is formedbetween the outer pipe and the inner pipe; and a fluid infusion pipe which communicates with the radial clearance is arranged at a joint part of the outer pipe and the inner pipe, and can inject firstfluid to the radial clearance, so that the first fluid can flow adhering the inner wall of the outer pipe. Through the adoption of the fluid infusion machine disclosed by the invention, the smooth flowing of high-concentration starch paste obtained through high-concentration starch milk gelatinization can be realized, starch liquefaction fluid is produced in a high-efficiency manner, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of starch liquefaction processing, in particular to a liquid replenisher, starch jet cooking equipment, a starch liquefaction device and a method for jet cooking liquefaction of high-concentration starch milk. Background technique [0002] In the process of producing starch sugar from starch, it is usually necessary to mix commercial starch with a water content of about 13-14% and water in a certain proportion to make starch milk, and then add a certain amount of starch liquefaction enzyme to the starch milk, and then pass through Jet cooking is used for gelatinization of starch, and then the high-viscosity starch paste is liquefied to obtain water-soluble dextrin or starch sugar with only one or several glucose groups. [0003] In the process of jet cooking and liquefaction of starch milk, under the current technical conditions, when the concentration of dry starch in starch milk reaches about 36%, if the concentrati...
