Abstract
The present invention relates to a making method of taro powder. The technological process comprises the steps of feeding, peeling, pelleting, air drying, dewatering, low temperature pressurization and slaking, pulverization, weighing and packaging. The present invention has a key point that the slaking temperature of a material can be controlled within the range of 80 DEG C to 100 DEG C in a working process of low temperature pressurization and slaking. Pressure is controlled within the range of 101.3 to 202.6KPa (1 to 2 atmospheric pressure). The taro powder made with the method has the advantages of high work efficiency and high quality of a made finished product and can keep the taste of a taro unchanged.
Description
The present invention relates to food-processing method, especially relevant with the taro meal preparation method.
Traditional taro meal preparation method and potato powder preparation method are similar.A kind of is to adopt peeling, cut (grain) sheet, dehydration is done in baking (solarization), the preparation method that gets product after the pulverizing, another kind then is to adopt making beating, filtering-depositing, anhydrate and shine the preparation method that dry grinding gets product, these two kinds of methods all exist certain problem in making the taro meal process, as then in baking process, making goods catch the barbecue smell with first method or tanning by the sun smell, and the distinctive fragrance of destruction taro, thereby product quality is descended, as use second method, the slurries that then form after making beating are difficult to dewater with conventional method, and often cause spray nozzle clogging owing to contain a large amount of strings in the slurry with spray drying process, make that production ten minutes trouble and efficient are low.
The objective of the invention is to provide a kind of preparation method of taro meal, it can overcome the shortcoming of above-mentioned conventional method, improves technical process, enhances productivity, and produces the taro meal that has good quality and comes.
The technological process of the inventive method comprises the peeling of selecting materials, the air-dry dehydration of pelletizing, low temperature pressurizing and ageing, air-cooled dehydration, pulverizing and weighing and bagging.In the peeling operation of selecting materials, select a big taro to clean after, the taro skin is gone most with abrasion peeling method or the cutter skin method of pruning.In the blank operation,, will remove the peel taro and be cut into particulate, particle diameter 10 millimeter with pelletizing machinery or universal cutter.In air-dry dehydration procedure, it is air-dry with taro to add wind with conveyer belt, and its water content is reduced to about 40%.In low temperature pressurizing and ageing operation, to the dehydration pellet pressurizing and ageing of heating, its temperature is controlled at 80 ℃~100 ℃ with screw propulsion equipment, and pressure is controlled at 101.3~202.6KP (1~2 atmospheric pressure).In air-cooled dehydration procedure, add wind with conveyer belt the slaking material is carried out air-cooled dehydration, its temperature is reduced to below the normal temperature, its water content is reduced to below 15%.In pulverizing process, with pulverizer air-dry grog is pulverized, its fineness is reached below 246 microns, (more than 60 orders).In the weighing and bagging operation, the taro of pulverizing by required weight weighing, and is packaged in jar, in the bottle or low paper, mould in the bag, promptly gets end product.
Producing taro meal with the inventive method has the following advantages: 1, raw material sector-style dry grinding again after maturation process, so the crush efficiency height, to pulverize quality good; 2, because the maturation process condition is the low temperature pressurizing and ageing, thus can avoid high temperature to the destruction of taro meal collastromin and too early efflorescence, thus guarantee that manufactured goods have taro " genuineness ".
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a process chart of the present invention.
As shown in Figure 1, technological process of the present invention is: 1. the peeling of selecting materials, 2. pelletizing, 3. air-dry dehydration, 4. low temperature pressurizing and ageing, 5, air-cooled dehydration, 6. pulverize, 7. weighing and bagging.In the peeling operation 1 of selecting materials, should select big taro as raw material (general heavily should reach more than 0.5 kilogram), taro should be cleaned in advance, the taro crust is gone most with abrasion peeling method or the cutter skin method of pruning again.In pelletizing operation 2, will remove the peel taro with pelleter or universal cutter and be cut into particulate, particle diameter 10 millimeter.In air-dry dehydration procedure 3, it is air-dry with taro to add wind with conveyer belt, conveyer belt is a Stainless Steel web plate conveyer belt, if the air-dry speed of design is 200 kilograms/hour, then belt length is generally 30 meters, transmission speed is 0.5 meter/minute, and its blowing blower fan is 30 ℃~60 ℃ adjustable hot blast units of classification, and the air-dry time of material on conveyer belt is 60 minutes; By air-dry, should make the material reduction water content of former water content 70%~80% is about 40%.In low temperature pressurizing and ageing operation 4, a kind of screw propulsion equipment is arranged, this equipment class is similar to the mud pressure pump, with it dehydration pellet is carried out screw extrusion and advances.In the extruding progradation, causing on the one hand heats up makes the pellet thermalization, in the pellet extruding advances pellet is carried out elementary pulverizing again on the other hand.It should be noted that, curing temperature definitely can not be too high, generally be controlled in 80 ℃~100 ℃, as when reaching more than 100 ℃, the taro meal of producing is used to make taro goods such as taro mud and will loses its due taro and stick with paste glue and fragrance, screw propulsion equipment pressure generally is controlled at 101.3~202.6KP (1~2 atmospheric pressure), and its curing temperature is low more, and then the material of slaking is good more to last end product quality.In air-cooled dehydration procedure 5, add wind with conveyer belt equally the slaking material is carried out air-cooled dehydration, conveyer belt is similar to operation 3 to the design of blower fan, and this operation should make the slaking temperature of charge be reduced to below the normal temperature, and its water content is reduced to below 15%.In pulverizing process 6, disintegrating apparatus can be selected the broken machine of common flour for use, and air-dry grog is pulverized, and makes its fineness reach (more than 60 orders) below 246 microns.In weighing and bagging operation 7, with Automatic weighing and packaging machine or manual weighing and bagging, packing container can adopt tin can, vial, also can adopt tin aluminium paper bag or plastic film bag.Packaged taro meal is finished product.
