Abstract
A freezing, vacuum drying process for efficient production of yam powder is disclosed, which features very short freeze-vacuum drying period and high productivity, considering the special viscosity of yam itself.
Description
The present invention relates to a kind of production and processing method of vacuum freezedrying food production processing method, especially freeze and vacuum dried Chinese yam powder.
At present, with vegetables, when fruit is cooked frozen dried food, all be material is cut into slices as far as possible, the silk or granule, quick-frozen is then sent to and is carried out freeze drying in the vacuum freeze drier.Doing like this is in order to reduce the volume of quick-frozen material as far as possible, can remove as early as possible when ice in the quick-frozen material is distilled in freeze dryer, thereby the shortening time enhances productivity.But when doing freeze-drying prods with Chinese yam, situation is just different, because Chinese yam itself has special mucilaginous substance, when Chinese yam is cut into slices, when silk or granule, mucilaginous substance is bonded together them again, make sheet, do not have the space between silk or the granule, from and form whole, these sheets after the quick-frozen, silk or granule form one and freeze piece greatly, when sending in the vacuum freeze drier freeze-drying again to, because volume is big, the cryodesiccated time is just very long, needs 30 several hrs ability dry usually, certainly uneven distribution is even owing to freeze greatly, the place that does not parch in addition often, general way all is that undried material is put together, following stove continues drying again.Nineteen ninety-five proposed the patent application of " active Chinese yam flour and manufacture method thereof " by Xu Heng will and Xu Hengjun, and patented, and the patent No. is 95111876.5, and this patent content is relevant with the present invention.
The production method that the purpose of this invention is to provide a kind of new freeze-drying yam flour, can shorten widely when cryodesiccated with, greatly improved the production efficiency of freeze-drying yam flour.
The object of the present invention is achieved like this: Chinese yam is cleaned peeling, be cut into segment or quick-frozen in the quick freezing repository is sent in the fritter sabot to cutter.In quick freezing repository, lay hammer bar type or beater disintegrating machine, pulverizer will pass through cleaning, reach food hygienic standard, the staff is under the situation of carrying out whole body winter protection preparation, in quick freezing repository that quick-frozen is good Chinese yam section or piece are pulverized it with pulverizer, sabot again, at this moment Chinese yam section or piece all are that loose granule freezes piece after crushed.So operation is until the consumption of getting freeze dryer one stove ready, and the freeze-drying production and processing is carried out in shove charge again.
Owing to adopt production method of the present invention, under identical output situation, only just can drying come out of the stove with 10 hours, and the dry uniform and complete that gets, not in the dead angle that need not melt down thoroughly, greatly improved production efficiency.
Realize that best way of the present invention is: 1. in order to alleviate severe cold in the quick freezing repository to staff's invasion and attack, temperature in the quick freezing repository is at shredding stage, need not control too lowly, the frictional heat that produces between pulverizer and the material when needing only pulverizing is unlikely material is dissolved; 2. make big feed hopper, give the pulverizer charging with automatic feeder, making big receiving hopper more temporarily stores the discharging of pulverizer, the staff just can monitor crushing process with monitor in the quick freezing repository outside, can reduce a staff like this holdup time in quick freezing repository, improve working conditions and environment.
Claims (1)
- A kind of production method of vacuum freezedrying food powder face, it is characterized in that: earlier with the material quick-frozen, keep its activity, in the environment of zubzero temperature, material is ground into granule and freezes piece, granule freezes loose adhesion between the piece, then its sabot is sent to and carried out freeze-drying processing in the vacuum freeze drier, thereby shortened the cryodesiccated production and processing time of frozen dried food, improved production efficiency.
