Abstract

The invention belongs to the field of food processing, and particularly discloses a granulation technology of onion powder, which comprises the following steps: taking the onion powder as a raw material, sealing the onion powder in a granulation pan to dry, spraying with a sizing agent in the granulation pan after drying, and inputting the hot air for drying, inputting cool air into the granulation pan to obtain a crude product, and then sieving the crude product to obtain a final product. The product of the invention has the advantages of moisture proofing, agglomeration resistance, prompt water solubility, heavy roasting savory smell and the like, and can be widely used in the family, the BBQ, and the soup production.

Description

A kind of prilling process of onion powder
(1) technical field
The invention belongs to food processing field, particularly a kind of prilling process of onion powder.
(2) background technology
Because onion powder existence itself is difficult for storage, uses shortcomings such as inconvenient, that the sense of taste is uncomfortable, before 5 years, American-European countries changes state and the using method of product by new technology, a large amount of raw materials from China's import preliminary working, carry out large-scale industrialization production, improved the sales volume of this product on market to a great extent, but the technology of this product at home a lot of factories test and be success.At present, the split granulating technique can be divided into 4 classes.
(1) paddling process.The paddling process granulation is to infiltrate certain liquid or binding agent in the solid-state fine powder and suitably stir, and liquid is contacted mutually closely with solid-state fine powder, generation cohesive force and form granule.The advantage of paddling process is that former is simple in structure, and single machine yield is big, and formed particle easily dissolves fast, drenched property is strong, and shortcoming is that uniform particles is bad, and formed granule strength is lower.
(2) compression moulding method.This method be will granulation powder material be limited in the particular space, by applying the dense state that external force compresses.This method has that adaptive capacity is strong, output is big, epigranular, good, the granulating rate advantages of higher of granule strength.
(3) spraying and dispersion vapodusting.This method is in particular device, makes the liquid phase or the semi-liquid phase material that are in the high degree of dispersion state directly become solid particle.The denominator of this spraying and dispersion atomizing comminution granulation is: but liquid feed must be that available pump is carried and disperse; Granulation process should be continuously usually, automation and large-scale operation; Granulating system must be designed to reclaim or to recycle the material end, carries phenomenon secretly with the attrition and the powder that solve material; Product granularity generally is limited in below 5 millimeters.
The advantage of this kind equipment is that the granulation process of material and dry run carry out simultaneously; Its shortcoming is that granule strength is lower, and granularity is less.
(4) the heat fusing method of forming.The heat fusing method of forming is to utilize the low melting point characteristic of product (generally being lower than 300 ℃), by special condensing mode, makes its condensation-crystallization become desired sheet, strip, bulk, shape such as hemispherical fused materials.
Because onion powder bonds easily, caking, heatproof are low, high temperature is easily stuck with paste, above method all can not be applicable to the onion powder granulation.
(3) summary of the invention
The present invention provides the prilling process of the onion powder of a kind of handling safety, quality of finished product good in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of prilling process of onion powder is raw material with the onion powder, comprises the steps:
(1) onion powder is dropped in proportion the oven dry of sealing granulation pot, require 120 ~ 140 ℃ of leaving air temps, 45 ~ 50 ℃ of outlet temperatures, 10 ~ 15 minutes time, oven dry back moisture requirement is below 4%;
(2) whitewash in the granulation pot in the oven dry back, and slurries are that liquid converted in the accent of carboxymethyl cellulose, constantly knock a pot body in the whitewashing process, and then the oven dry in 15 ~ 20 minutes of logical hot blast;
(3) after the oven dry, same cool breeze in the granulation pot, leaving air temp is below 40 ℃, after 10 ~ 12 minutes thick product is poured out in the granulation pot;
(4) thick product is sieved, screen cloth is 30 ~ 100 orders, obtains product after sifting out powder, packing.
Slurries of the present invention are that mass fraction is 3 ‰ carboxymethyl cellulose.
The present invention is by using the granulation pot of sealing, to the adjusting of leaving air temp, EAT and to the control of raw material moisture, overcome that onion powder bonds easily, caking, heatproof are low, the easy shortcoming such as paste of high temperature.
The points for attention of the present invention in operating process are: (1) detects material (onion particle) more than unit weight 240 ~ 270ml/100g; (2) note the material color, should control in milky to light yellow.
The present invention has filled up the blank of domestic onion powder granulating technique, overcome the shortcoming that fluid bed bubbles easily, strengthened gas-solid contact and mixing, made operation and one such as the mixing of whole granulation process collection, kneading, granulation, drying, system is airtight, the handling safety no dust pollution.
Product of the present invention have protection against the tide, anti-caking, speed water-soluble, strong characteristics such as roasting fragrance are arranged, be widely used in the making of family, barbecue, soup class.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is process flow diagram of the present invention.
(5) specific embodiment
Embodiment 1:
At 1 m 3The granulation pot in the onion powder of disposable input 240kg, feeds 130 ℃ hot blast 15 minutes, 0.5 liter/minute of the average speed of whitewashing, whitewashing amount 25kg, finished product unit weight 250ml/100g goes out finished product 180kg.
Embodiment 2:
At 2 m 3The granulation pot in the onion powder of disposable input 480kg, feed 120 ℃ hot blast 20 minutes, 0.5 liter/minute of spouting velocity, whitewashing amount 50kg, finished product unit weight 230ml/100g goes out finished product 350kg.

Claims (2)

1. the prilling process of an onion powder is raw material with the onion powder, it is characterized in that: comprise the steps:
