Several food screening equipment analysis and comparison
Food screening plays an indispensable role in agricultural breeding and quality inspection. As a result, screening-related equipment such as powder screening, electric powder screening, horizontal format sampling, and Zhongding sampling are also emerging. Equipment, new standard powder screening, etc., are key equipment for grain screening and seed breeding. Each of these devices has its own merits, and its principle parameters are the same. We need to select suitable equipment according to actual conditions during the actual practice.
Here we will analyze several instruments that are frequently used during the quality inspection of breeding.
Horizontal format sample splitter: The horizontal format sample splitter is used for sample separation of seeds and the like, and evenly divides one sample into two parts and divides the samples several times to obtain a plurality of equal samples.
Electric powder test sieve: Electric powder test sieve according to GB5507-85 "food oil inspection, powder thickness determination method" national standard developed a kind of powder thickness measurement of special equipment. The electric powder test screen produced by Top Instrument is compact in structure and easy to operate. It is an irreplaceable product for the determination of powder thickness by current national standards. Can be widely used in grain and oil testing departments and flour processing companies.
Round powder test sieve: Round powder test sieve is one of the powder test sieves, and the round powder test sieve is powdered according to the new national standard GB/T5507-2008 "Determination of grain and oil test powder thickness and fineness". Test sieve. The principle is that the sample is sieved on sieves of different specifications to achieve different particle separation. Calculate the thickness of powdered grain according to the amount of residue on the screen. Its technical parameters are as follows: working power: AC220±10V 50Hz; input power: 60W; screen size: φ300mm×30mm; screen size: CQ: 10, 16, 20, 27; CB: 30, 36, 42; 50mm; Rotation speed: 260r/min; Sample weight: 50.0g; Timing time: 0-900s.
Feature:
Wood glue is also called white glue, this product is water polymer emulsion, has the characteristics of high viscosity, non-toxic, not smelly, dry quick and so on
Main Component:
Polyvinyl acetate emulsion unit, water, filler.
Scope of application:
50% solid content mainly for water-solubility construction coating raw material, to the lumber, the paper, the leather, the linter fabric, the cement and the foam plastics and so on has the good binding property, may serve as the books wireless to bind, cigarette, boding and sizing of fabrics.
40% solid content is mainly for wood processing, cigarette and bonding and sizing of fabric. 30% solid content mainly use as sticks for paper, small lumber, available in paper processing (paper pulp chemical additive, paper soaking, spreads cloth to help medicinal preparation), fabric processing, cement intensifier, handicraft production and culture and education office supplies bond.
25% solid content mainly uses in the officing, printing, the paper box processing, the low-grade paper tube processing, the handicraft and the paper caking and so on.
Using Method:
1, The joint surface must be clean, dry.
2, Spreads the glue on the joint surface, presses till solidification, maintains for 24 hours under the room temperature to achieve the use intensity.
Warning:
1, The iron barrel packing is strictly prohibited
2, The using temperature should be 10 ℃ or above; After agglutination product before solidification, also should maintain in 10 ℃ above. Otherwise will cause viscosity drop if the emulsion not form good cover.
3, Wipe the bottle mouth clean after use, cover rapidly for usage next time.
4, IF the glue with half coagulation condition please mix evenly, does not affect the viscosity.
5, The water content of wood should be controlled between 8~15%,more or less content will affect the viscosity quality.
6, Do not get into mouth, keep our reach of kids.
Storage and packing:
1, The product should be stored at temperature 5~37℃ in sealed non-metal container, prevent from freeze and high temperature. The shelf life is one year from date of production. It is available to use based on passing of the test if being beyond the shelf life.
2, If the glue slightly freezes, should place in 30~40 ℃ greenhouses the full alleviation, and stirs evenly, does not affect the use. If the glue long time receives seriously freezes, cannot alleviate, appears agglomerates, the lamination even emulsion breaking, then cannot continue to use.
3, Preserve and transport as flammable products.
