Hydrolysate Spray Dryer

(Hydrolysate Powder) Spray Dryer is the most widely used process in liquid shaping technology. It is suitable for producing powder and granules solid products from solution, emulsion, soliquoid, and pumpable paste materials. Therefore, when the particle size, final moisture, bulk density and granules shape meet the accurate standard, centrifugal spray drying is a ideal drying process.

Description

Description

Working Principle

Liquid material is atomized through a special pressure nozzle with a high-pressure pump. Hot air enters the dryer after being adjusted by an air distributor. The material and hot air is mixed in the dryer, rapidly carries on heat and mass transfer. Powder or granular products are produced in a very short time. Products with larger particles size are discharged from the bottom of the dryer, smaller particles enter the cyclone with hot air. The exhaust gas is discharged into the air after dust removal in a scrubber. The dryers can be divided into high, middle and low-pressure spray dryers according to different pressures of atomization, while taking into account different flow fields, they are divided into co-current, fountain mode and counter-current spray dryers.

Features of spray dryer

a. High drying efficiency

b. The finished powder or granule has good uniformity, fluidity and solubility.

c. Simple and convenient operation

d. Using a mechanical atomizer and driven by gears, the speed is stable to ensure uniform droplets.

e. The direction and angle of the hot air distributor can be adjusted to ensure that the droplets are in full contact with the hot air.

f. The connecting elbow is made of sanitary steel pipe and should be smooth enough to avoid material blocking in the pipe.

g. Widely used: food, chemicals, ceramics, basic dyes, etc.

Applicable Materials

Hydrolysate Powder

Hydrolysate refers to any product of hydrolysis. Protein hydrolysate has special application in sports medicine because its consumption allows amino acids to be absorbed by the body more rapidly than intact proteins, thus maximizing nutrient delivery to muscle tissues. It is also used in the biotechnology industry as a supplement to cell cultures. In the December 2013 edition of The International Journal of Food Science and Technology, hydrolysate was shown to be rich in L-aspartic acid and the necessary minerals manganese and selenium.

Food: Amino acid, vitamin, egg powder, bone powder, protein, milk powder, blood powder, soy sauce powder, coffee, tea powder, glucose, pentadiene carboxylic acid, pectin, flavours, vegetable juice, yeast, starch, etc.

Ceramic: Alumina, zirconia, magnesium oxide, Titania, pottery clay, china clay, all kinds of magnetic porcelain and metal-oxides, etc.

Chemical: Aluminum polychloride, disperse dyes, reactive dyes, organic catalyzer, white carbon black, washing powder, zinc sulfate, silica, sodium metasilicate, potassium fluoride, calcium carbonate, potassium sulfate, inorganic catalyzer, wasted liquid, etc.
