Purple sweet potato cooked whole flour production line

Abstract

The invention provides a purple sweet potato cooked whole flour production line, which mainly consists of a cyclone stone removing cleaning machine, a cage type cleaning machine, a weighing instrument, a rotary steam peeling machine, a peel brushing cleaning machine, a quality inspection conveyor, a slicing machine, a blanching machine, a cooling machine, a steaming and boiling machine, a paste preparing machine, a rotary drum dryer, a diaphragm crushing machine, a sieving machine, a packaging machine and the like, wherein conveyors or pumps are arranged between the devices and connect the devices to form the production line. The purple sweet potato cooked whole flour production line has the advantages that under the condition of not using any chemical synthetic agents, purple sweet potato cooked whole flour with stable quality can be safely, sanitarily and continuously produced in a large scale; the reconstitution property of the product is good; in addition, more nutritious ingredients can be maintained in the product, so the flavor and the mouthfeel are more similar to those of fresh purple sweet potatoes; in addition, the equipment configuration is economic and reasonable; the operation reliability is high; the maintenance cost is low; and the automation degree is high.

Description

Technical field [0001] The invention relates to a production equipment for deep processing of potato raw materials, in particular to a production line equipment for continuous scale production of ripe purple potato powder. Background technique [0002] At present, the known purple sweet potato powder generally adopts traditional raw powder processing methods and equipment, that is, mainly by hand, supplemented by simple machinery, and the purple sweet potato is cleaned, peeled, sliced, dried in the sun or kang-dried, crushed, The raw powder of purple sweet potato is obtained after sieving. Purple potato starch has many defects such as more impurities, poor rehydration, jerky taste, etc., and the output is small. The important thing is that the product is in the whole production process, which is the basic requirement for food - food safety and sanitation, it is impossible Get a reliable guarantee. In recent years, new explorations have been made on the processing methods a...

Problems solved by technology

But this production method and equipment really have many questionable problems, as: 1, in its backfilling process, adopt the result of 1300-1500 rev / min high-speed mixer to stir, should make the cell wall damage of purple sweet potato serious, in it The loss of the unique flavor substances contained will be volatilized and lost in the high-temperature hot air environment in the subsequent drying process, making the unique flavor of purple sweet potato weak; 2. In its backfilling process, it is necessary to use a large amount of dried purple sweet potato The whole potato powder is mixed in the purple sweet potato puree to greatly reduce the moisture content of the purple sweet potato puree, so that the purple sweet potato puree can be dispersed into fluffy and moist granules to meet the needs of entering the state of air drying. In fact, the purple sweet potato produced by this method The whole powder is produced in a high temperature and dry environment after repeated cycles

The purple potato powder containing a large amount of carbohydrates is produced by backfilling and drying technology: first: the anthocyanins contained in the purple potato, which are beneficial to human health, have a large variation loss; second: the purple potato powder has been dried at high temperature for many times In the process of processing, it is easier to generate acrylamide which is harmful to human health; third: in the process of processing, the application of chemical synthetic agents such as color-protecting agents and leavening agents makes the finished purple sweet potato flavor weak and poor in taste; 3 , The spin flash drying method described in it is actually a kind of air drying. This drying method and supporting equipment are used in the drying process of producing purple sweet potato powder. The equipment investment is large, the floor area is large, and the dust pollution is relatively serious. The energy consumption is also very large, resulting in a large waste of heat / electricity energy and high production costs
