Description

Low free rate filing machine

Technical field:

The utility model relates to a file grinding machine with a low free rate, which is mainly used for crushing raw potato raw powder, and can also be used for crushing roots and tubers of other crops, and can be used alone or matched with other crushing equipment.

Background technique

At present, crushers and rasp mills are widely used in domestic potato starch processing.

Chinese patent CN200420011056 is a file grinder, which quickly files and breaks the potato pieces into fine powder through the fine saw teeth of the saw blade assembly, so that more starch granules wrapped in the cells are freed. Chinese patent CN200620120495.2 is a direct-coupled filing machine, which is basically similar to the above-mentioned patent.

Chinese patent CN201420507711.3 is a self-driven filing machine, which is characterized by: a rotor assembly is fixed on the inner wall of the drum, a stator assembly is fixed on a fixed shaft, and there is a certain gap between the stator assembly and the rotor assembly to form a magnetic field magnetic gap , when the stator winding coil is connected to alternating current, the rotor assembly drives the drum to rotate around the stator assembly, and drives the filing saw blade to complete the filing and crushing of potato pieces.

All these crushers and rasp mills increase the free rate of starch through filing so that more starch can be freed. Moreover, the motor power of the above rasp grinder is also relatively large, and the energy consumption is very high.

However, during the processing and production of raw potato powder, it is necessary to disintegrate the raw materials to reduce the crushed particle size of the material and reduce the free rate of starch to avoid the loss of nutrients. In the production process of raw potato powder, the raw material block diameter is relatively large. Using the original processing technology of repeated filing or secondary filing, the free rate of starch is high, the loss of nutrients, and the energy consumption is also very high. In order to reduce the free rate, reduce the loss of nutrient components, and reduce energy consumption, the method of micro-shearing and cracking can minimize the free rate of starch, reduce the loss of nutrient components, and make potatoes a staple food. At the same time, energy consumption can be effectively reduced.

Contents of the invention

The purpose of this utility model is to design a low-free-rate filing machine suitable for potato powder processing based on the above-mentioned existing technical conditions. Using this file-grinding machine can effectively improve the crushing efficiency of raw materials, reduce the starch free rate, and effectively Reduce energy consumption.

The purpose of this utility model is achieved through the following technical solutions:

A low free rate filing machine, including a frame, a feeding mechanism, a crushing chamber installed on the frame, an impeller, a file disc and a discharge port arranged in the crushing chamber, wherein: the feeding mechanism adopts a reducer Driven cantilever feeding auger, the front end of the feeding auger is located at the inlet of the crushing chamber; the impeller is an edge blade structure, the impeller is connected to the main shaft of the impeller through a taper sleeve, and the main shaft of the impeller is connected to the motor through a transmission mechanism (that is, the main shaft of the impeller Driven by a transmission mechanism and a motor); the file disc is a near-arc plate structure composed of multiple cutter discs, which is installed at the bottom of the crushing chamber, and each cutter disc is provided with a knife slot for installing a saw blade and a feeding chute .

The blades on the impeller lean forward in the direction of rotation at an angle of 5°-15°.

The main shaft of the impeller is connected with the motor through a belt drive, and is equipped with a moving slider type belt tensioning mechanism.

The cutter head can be in the following two structural forms (see Figures 4 and 5). One structure is: one side of the cutter head is a straight-edge structure, and the other side is an open trough structure, and the upper plane of the cutter head is equipped with a saw blade. The bearing groove.

Another structure is: the two sides of the cutter head are symmetrical, and both are open-type cutting chute structures, which are spliced with adjacent cutter heads to form a strip-shaped cutting chute, and the upper plane of the cutter head is provided with a knife-bearing groove for installing the saw blade.

The saw blade is a double-sided sawtooth structure, which is directly clamped in the knife holder groove.

The crushing principle of the utility model is as follows: the material enters the crushing cavity through the feeding auger, driven by the motor and the pulley, the impeller rotates at high speed, driving the potato pieces to move quickly. The blades on the impeller are tilted forward at a certain angle to the direction of rotation. When the impeller rotates at a high speed driven by the main shaft, the force of the blades tilting forward is decomposed into forward thrust and downward extrusion force acting on the material. , under the combined action of the impeller and the saw blade, micro-shearing and crushing of the material is formed. Under the joint shearing action of the impeller and the saw blade, the potato pieces are broken into fine particles. The feeding auger is cantilever type, the bearing chamber and the reducer are at the same end of the auger shaft, and the other end is suspended in the air, which will not affect the feeding and avoid material blocking. The shape of the saw blade is a double-sided sawtooth type, with sawtooth on both sides. When working, one side of the sawtooth works. After one side of the sawtooth is worn, you can turn the saw blade and continue to use the other side of the sawtooth. The installation method of the saw blade adopts the plug-in type, which is convenient for installation, replacement and maintenance. The file disc is a nearly arc-shaped structure composed of multiple cutter discs, and each cutter disc has a knife receiving groove and a feeding groove. The cutter head can be designed into two structures (see Figure 4 and Figure 5). The installation method of the cutter head is similar to that of the saw blade. It adopts the plug-in mounting method, which is very convenient to install. It can be inserted directly from the bottom of the impeller without removing the impeller.

When the equipment is in working condition, the impeller rotates at a high speed, and the raw material enters the crushing cavity from the feed port through the feeding auger, and is crushed into 1-3mm particles under the shearing and extrusion action of the impeller and the saw blade. Then it falls through the discharge port and enters the next process.

Compared with the file grinder in the prior art, the file grinder of the utility model not only has a low starch free rate, but also greatly reduces energy consumption when processing whole potato powder. At the same time, the structure has also been greatly improved. The structure of this filing machine is simpler and lighter, and it does not need a screen to avoid material blocking. The number of saw blades is greatly reduced, making it more economical and practical.
