Crystallizing tank for boiling sugar

Abstract

The invention relates to the field of sugar-producing devices and particularly relates to a crystallizing tank for boiling sugar which is smooth in operation, good in sealing performance, good in massecuite circulation, uniform in concentration, little in sugar crystal grain abrasion and capable of effectively saving the time of sugar boiling. The crystallizing tank comprises a tank body (1), wherein an evaporator (2) is arranged inside the tank body (1), a discharging port (3) is arranged at the bottom of the tank body (1), a feeding port (4) and a blow-down pipe (5) are arranged on the side wall of the tank body (1), and a driving device is arranged on the upper portion of the tank body (1) through a supporting seat (6); a heating chamber is arranged on a position inside the tank body (1), the position corresponds to the evaporator (2), and an evaporating chamber is arranged on the upper portion of the evaporator (2); the heating chamber is provided with and respectively communicated with a steam input pipe (7) and a seed input pipe (8); the driving device is connected with a main shaft (9) extending to the inside of the tank body (1); a forced-circulation blade (10) arranged inside the center of the evaporator (2) is installed at the end of the main shaft (9) which extends to the inside of the tank body (1); and one side of the supporting seat (6) is connected with a vacuum tube (11).

Description

technical field [0001] The invention relates to the field of sugar making equipment, in particular to a sugar boiling crystallization tank. Background technique [0002] The crystallization tank is a kind of crystallization equipment, which is widely used in the fields of material mixing, cooling and freezing, and crystallization of finished products in pharmaceuticals. In addition, it is also widely used in dairy industry, food, chemical industry, beverage and other industries, especially for sugar enterprises. Said that the crystallization tank is an indispensable sugar refining equipment. [0003] Sugar boiling is a key part of the production process of sugar enterprises. Its main task is to concentrate syrup (or molasses) to a certain degree of supersaturation in the sugar boiling tank, to precipitate sucrose crystals that meet the requirements and to grow the crystals. , boiled into a good massecuite; after that, crystallization and mother liquor were removed with a ce...

AI Technical Summary

Problems solved by technology

[0004] Although the automatic sugar cooking system is adopted, there are still many problems in the traditional crystallization tank using this system. For example, there is no forced circulation device in the traditionally designed and manufactured crystallization tank, and the circulation of the internal massecuite is a natural circulation powered by temperature difference. type

This natural circulation mode has a low heat transfer rate, resulting in uneven grain size, dark color, low crystallization rate, and long crystallization time when the massecuite crystallizes; the concentration of the material in the tank is uneven, and the circulation of the massecuite in the tank is poor. This leads to problems such as long cooking time, high energy consumption, and increased color value of finished sugar.
