A kind of preparation technology of solid lactic acid

Abstract

The invention relates to the field of biochemical manufacturing, specifically a preparation process of solid lactic acid, including a grinding part and a reaction kettle, both of which are fixed on the top of the same installation bottom plate, and the top side of the inner wall of the reaction kettle is connected to the The rod is movably connected with a backstop, and one side of the grinding part is provided with a grinding disc. By setting the non-return device, at the moment when the motor without a diode is stopped, due to the rotational inertia of the material to be stirred, the stirring rod still has a tendency to twist at the moment when the output shaft of the motor stops, so that it still maintains its stability after stopping the energy supply. Rotating state, and then protect the brush of the motor to prolong the life of the motor, and eliminate the existing relative torsion between the stirring part and the object to be stirred, and prevent the relative torsion from generating air bubbles. In the case of silica and calcium lactate, the reinforcement bolt combined with the mounting groove and mounting plate makes the grinding head easy to remove frequently.

Description

technical field [0001] The invention relates to the field of biochemical manufacturing, in particular to a preparation process of solid lactic acid. Background technique [0002] Natural lactic acid is a natural inherent component in dairy products. It has the taste of dairy products and good antimicrobial effect. It has been widely used in formulated yogurt cheese, ice cream and other foods, and has become a popular dairy product sour agent. Due to lactic acid The mild and moderate sour taste can also be used as the first-selected sour agent for carefully formulated soft drinks and fruit juices. However, in the production process of existing lactic acid, the cooperation between the reactor used in the current process and other procedures in the process still has the following problems: [0003] Since lactic acid is a liquid under normal conditions, it is not conducive to transportation and storage. There is a stirring operation in the production process of solid lactic acid...

AI Technical Summary

Problems solved by technology

[0003] Since lactic acid is liquid under normal conditions, it is not conducive to transportation and storage. There is a stirring operation in the production process of solid lactic acid. However, during the stirring process, the motor without a diode is stopped at the moment, due to the rotational inertia of the material to be stirred, the stirring rod The output shaft of the motor still has a tendency of torsional movement at the moment of stop. If the construction period is tight, it will be operated when the object to be stirred has not completely stopped rotating, so that the object to be stirred will have a certain movement trend in the opposite direction. In the long run, it is easy for the motor and its output. The shaft causes certain damage, which reduces the service life of the device components. When grinding silicon dioxide and calcium lactate, the grinding head is expensive because of its hard texture. When disassembling the grinding head in the existing grinding device, only fastening is used. The connection method cannot withstand frequent disassembly, which affects the working efficiency of the device, and during the screw installation process, the hard mounting plate makes it impossible to fully guarantee the safety and stability of the single screw hole fastening method;
