Detailed Description

The invention will be further described in detail with reference to the drawings and the detailed description below, in order to further understand the features and technical means of the invention and the specific objects and functions achieved.

As shown in fig. 1,2 and 8, the present application provides:

The utility model provides an automatic grinding device of health food material, includes bearing mechanism 1 and sets up the mechanism that rolls at bearing mechanism 1 top, and bearing mechanism 1 has the bearing groove 111 of opening up, the mechanism that rolls has can the butt at the tank bottom of bearing groove 111 and along the roller 21 that rolls of bearing groove 111 length direction removal, and roller 21 is when bearing groove 111 removes to the opposite side, and bearing groove 111 deflects towards the direction that roller 21 removed, and roller 21 butt is at the tank bottom of bearing groove 111 all the time.

As shown in fig. 5, the rolling mechanism includes a bracket 22, and a ball screw assembly 23 provided on the bracket 22, the ball screw assembly 23 having a working end movable in a length direction of the supporting groove 111, the working end of the ball screw assembly 23 being provided with a slide cylinder 24, the working end of the slide cylinder 24 facing downward, the working end of the slide cylinder 24 being provided with a rotation seat 25, and the rolling roller 21 being rotatably provided on the rotation seat 25.

When the roller 21 is required to move in the horizontal direction, the sliding table cylinder 24 is started, the working end of the sliding table cylinder 24 can enable the rotating seat 25 to move downwards, and then the roller 21 on the rotating seat 25 can be abutted against the bottom of the supporting groove 111 in the longitudinal direction.

Before the work, put in the bearing groove 111 with food material, start rolling mechanism for roll 21 removes along the horizontal direction, and the bearing groove 111 can be along the direction of movement slope of roll 21 simultaneously, and then makes the material of placing in the bearing groove 111 can slide to roll the direction of roll 21, makes roll 21 when removing to the opposite side, rolls the roll 21 can cooperate with the tank bottom of bearing groove 111 in order to roll the material, can effectively prevent the material gathering in one side and can't be rolled the problem.

In this embodiment, the grinding roller 21 capable of flexibly moving along the horizontal direction is accurately abutted in the supporting groove 111 of the supporting mechanism 1, so that when the grinding roller 21 moves reciprocally along the horizontal direction, the supporting groove 111 can cooperate with the movement thereof, and the swinging of the grinding roller to the two sides is realized reciprocally. This oscillation not only brings about the movement of the holding tank 111 itself, but more importantly it allows the material placed in the holding tank 111 to move reciprocally therewith.

This reciprocating material condition provides a wider crushing space for the crushing roller 21, ensuring that the crushing roller 21 which is in close abutment with the backup groove 111 and moves can crush the material in the sheave sufficiently and uniformly. The improvement not only remarkably improves the rolling efficiency, but also is more critical in effectively solving the problem that the compression roller in the existing rolling device cannot fully roll materials due to uneven material distribution or immobility. Through the innovative design, the rolling process is optimized, the processing quality of the material is improved, and more reliable guarantee is provided for subsequent processing and use.

As shown in fig. 3, a collecting cavity 112 is arranged at the bottom of the supporting groove 111, a screen material hole 113 is arranged between the supporting groove 111 and the collecting cavity 112 in a rectangular array, and when the supporting groove 111 deflects to two sides, materials with diameters smaller than that of the screen material hole 113 fall into the collecting cavity 112.

Food materials that have reached the roller compaction particle size fraction, if repeatedly rolled, may have the following problems:

Loss of nutritional ingredients: prolonged crushing or excessive grinding may destroy nutritional components such as vitamins and proteins in the food product. These nutrients may be destroyed or lost during the over-treatment process, thereby reducing the nutritional value of the food product.

Taste change: the size and texture of the food particles have a great influence on the mouthfeel. If the particles are excessively crushed, the mouthfeel of the food may become too fine or powdery, and the original mouthfeel characteristics are lost.

Structural failure: excessive rolling may damage the internal structure of the food product, losing its original shape or texture. This may be disadvantageous for certain foods that require maintenance of a particular morphology.

Flavor change: the flavor of food is closely related to its composition and structure. Excessive rolling may alter the flavor characteristics of the food product, either losing its original flavor or producing an undesirable taste.

The processing efficiency is reduced: if the required particle size has been reached, the continuous rolling will not only bring about a better effect, but may lead to an increase in processing time and waste of energy, thereby reducing the processing efficiency.

Therefore, in the food processing process, the rolling degree should be reasonably controlled according to the characteristics and processing requirements of the food, so as to avoid adverse effects on the quality and taste of the food caused by excessive rolling. Meanwhile, the nutrition and flavor changes of the food should be closely paid attention to in the processing process, so that the final product meets the requirements and expectations of consumers.

Through setting up the collection chamber 112 in the bottom of bearing groove 111 to set up sieve material hole 113 between bearing groove 111 and collection chamber 112, make bearing groove 111 when controlling reciprocal swing, the material is reciprocating motion equally in bearing groove 111, thereby play the effect to the material screening, make the diameter be less than the material of sieve material hole 113 can pass sieve material hole 113 and fall in collection chamber 112, avoid having reached the material of rolling fineness repeatedly by rolling, can ensure that the material in the collection chamber 112 is through fully rolling and reaching the fineness requirement, can also reduce unnecessary energy consumption and equipment wearing and tearing, thereby improved whole device's work efficiency and life.

As shown in fig. 2 and 3, the screen openings 113 are located in the center of the holding tank 111, and the material having a smaller diameter than the screen openings 113 passes through the screen openings when the food material moves in the deflected holding tank 111.

The material flow state changes during the reciprocating tilting of the holding tank 111, but in any case, since the screen openings 113 are located in the central position of the holding tank 111, they can always be in the path of the material flow. In this way, when the particle diameter contained in the material reaches a predetermined level, the particles can stably pass through the sieve openings 113 and fall into the collecting area below.

The design ensures the stability and continuity of the screening process and improves the screening efficiency. Since the screen openings 113 are always in the central region of material flow, they can maximize the capture of satisfactory particles, reducing the likelihood of screen leakage and false screening. Meanwhile, as the material can uniformly pass through the sieving holes 113 in the sliding process, the problem of nonuniform sieving caused by nonuniform material distribution is also avoided.

As shown in fig. 9 and 10, the aperture of the screen hole 113 can be adjusted.

The screen hole 113 has an adjustable aperture. This feature allows the screen openings 113 to be flexibly adjusted to accommodate different particle sizes or different screening accuracy requirements. By adjusting the aperture size, the speed and number of the material passing through the screening holes 113 can be precisely controlled, thereby realizing finer and more efficient screening effect.

Having adjustable aperture screen openings 113 not only increases the flexibility and adaptability of the screening process, but also enhances the practicality and economic benefits of the overall screening apparatus.
