Screening equipment has many applications in the food industry. Below Coreal Machinery summarizes some screening equipment applications for you. These devices solve different problems when used.
Working principle: The excitation force generated by the symmetrical vibration motor on both sides generates a combined force, the material is thrown up on the screen surface and moves forward, and the material passes through the screen to achieve screening.
Features: Suitable for screening, grading, and impurity removal of larger particle materials.
Problems solved:
Raw material grading: Grain, beans, nuts and other raw materials are graded according to particle size to make the product specifications uniform and facilitate subsequent processing and packaging. For example, in rice processing, rice of different particle sizes can be separated to improve the quality of rice.
Remove impurities: It can effectively remove impurities such as stones, soil, metals, etc. in the raw materials to ensure the hygiene, safety and taste of food. For example, in flour production, impurities mixed in wheat can be removed to improve the purity of flour.
Working principle: The eccentric blocks installed above and below the vibration motor shaft are used to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then this motion is transmitted to the screen surface, so that the material can do an outward expansion involute motion on the screen surface, and finally achieve the purpose of screening.
Features: Widely used, particles, powders, and slurries can be used.
Problems solved:
Screening: Suitable for fine grading and screening of powder and granular materials. For example, in the production of condiments, chili powder, pepper powder, etc. can be screened according to different mesh sizes to meet the requirements of different customers for product fineness.
Prevent agglomeration: For some materials that are easy to agglomerate, such as milk powder, starch, etc., the vibration mode of the rotary vibrating screen can effectively break up the agglomerates and ensure the screening effect.
Working principle: The motor is used to drive the fan blades on the main shaft to rotate. Under the action of the vortex wind force, the material is fluidized on the surface of the screen, and the material is screened through the screen.
Features: Especially suitable for screening of materials with very light specific gravity.
Problems solved:
High-fineness screening: It can efficiently screen high-fineness materials. For example, in the production of Chinese medicine powder, the ultra-finely crushed Chinese medicine powder can be screened into different fineness grades to meet the production requirements of Chinese medicine preparations.
Prevent dust from flying: The entire screening process is carried out in a closed state, which effectively prevents dust from flying out, improves the production environment, and reduces material losses.
Working principle: Imitating the manual screening action, the screen body makes a reciprocating swinging motion, and the material continuously rolls and slides on the screen surface to achieve screening.
Features: Suitable for screening of irregular or brittle materials, and the shape of the material is not damaged during the screening process.
Problems solved:
Screening of brittle materials: The screening process is relatively gentle and causes less damage to the material. It is suitable for graded screening of some easily broken and easily damaged materials, such as monosodium glutamate, chicken essence, salt, etc.
Working principle: Use a single motor or dual motors to generate exciting force to make the material pass through the screen quickly.
Features: Quick impurity removal
Problems solved
Quick impurity removal: For example, in a bakery producing bread, the flour uses a check screen before entering the mixer, which can quickly remove large lumps of flour, ensuring that the materials in the subsequent production process meet the production requirements, which helps to improve product information.
