Pig blood powder is a great animal feed additive. According to measurements, each kilogram of blood powder can produce 41 kilocalories of digestive energy and is rich in crude protein. Adding appropriate blood powder to animal feed such as chicken, pig, and cow can promote animal growth and shorten the feeding cycle. When slaughtering, put pig blood into a bucket, add 0.5-1.5% whole blood weight of quicklime before coagulation, stir evenly, wait for about 1 hour for the blood to solidify, then add 28% bran of equal weight, mix well with an iron shovel, spread it flat on a cement ground and dry it in the sun. The thickness should not exceed 3cm, and stir 6-7 times a day. After drying, crush it into pig blood powder. Pig blood powder is not easy to store for a long time. Those without added quicklime can only be stored for one month, while those with added quicklime can be stored for one year. After drying, pig blood powder should be sealed in plastic bags to prevent moisture and deterioration. A dryer is needed in the production of pig blood powder, and a high-speed centrifugal spray dryer is recommended. Directly convert pig blood from liquid to solid powder.

The centrifugal spray dryer is an open cycle, centrifugal atomization.

working principle:

The heat carrier is filtered by an air filter, sucked in by a blower, heated by a heater, and enters the pig blood powder drying equipment through a hot air distributor. The slurry is sent by a peristaltic pump to a high-speed rotating centrifugal atomizer, where it is dispersed into uniform small droplets under centrifugal force. In the centrifugal spray drying chamber, the small droplets are fully contacted with the heat carrier, heat exchange is carried out along its specific path, and then dried into products, which are separated through the cyclone separator (bag type dust collector, water film dust collector). The solid materials are collected, and the carrier is filtered through the bag type dust collector and the moving water film dust collector before being discharged. The entire equipment is easy to clean, operate, and has no dead corners.

characteristic:

The spray dryer has a fast drying rate and greatly increases the atomized area of the feed liquid. In the hot air flow, 95%~98% of the water can be evaporated instantly. It only takes 5-15 seconds to complete the drying process and has the characteristic of instantaneous drying.

The special air distribution device of the spray dryer effectively reduces the resistance of the equipment.

The production process of spray drying equipment is simple and suitable for continuous control production. The liquid with a moisture content of 40~90% can be dried into powder at one time to reduce crushing and screening processes and improve product purity.

The material completes the drying process in a short period of time, adapts to the boring drying of thermal sensitive systems, and can maintain the color, aroma, and taste of the material.

The product has good dispersibility, fluidity, and solubility, and the particle size and looseness of the product can be adjusted within a certain range.
