Problems solved by technology
The process of drying apple pomace at one time does not have a crushing process. Therefore, the drying process is difficult to control, the drying efficiency is low, the production efficiency is low, the product quality is unstable, and it is easy to appear coking or undried, resulting in a large resource utilization rate. reduce, causing huge waste and polluting the environment

Embodiment 1
[0029] The method for secondary drying apple pomace, its technological method comprises following technological process:
[0030] (1) One-time drying] the apple pomace after squeezing the juice is continuously dropped into a drying furnace for drying. The volume filling rate of the apple pomace in the furnace is 60%, and the temperature of the drying furnace is maintained at 700° C. with hot air. 5 minutes;
[0031] (2) Cooling and evaporation In the cooler, the once-dried apple pomace is cooled and evaporated from top to bottom, and the cold air is countercurrently flowed from bottom to top, so that the temperature of the pomace is reduced to below 50°C;
[0032] (3) The rotary knife pulverizer of 1500 rpm for pulverization is used to pulverize 80% of the apple pomace after cooling and evaporation to 6-10mm;
[0033] (4) Secondary drying Put the pulverized apple pomace into the drying furnace, the apple pomace filling rate is 60%, maintain the temperature with hot air at 80°...

The invention discloses a method for secondarily drying apple pomace, and belongs to the technical field of feed production. The method comprises the following technical processes of (1) primary drying: drying the apple pomace for 5 to 30 minutes under the condition of 490 to 850 DEG C, wherein the volume filling rate of the apple pomace is 30 to 75 percent; (2) cooling evaporation: performing cooling evaporation to the temperature being 60 DEG C or below; (3) crushing; crushing 60 percent or above of the apple pomace to 3 to 15mm; (4) secondary drying: performing drying for 5 to 30 minutes under the condition of 60 to 250 DEG C, wherein the volume filling rate of the apple pomace is 30 to 75 percent; (5) cooling evaporation: performing cooling evaporation in a cooling evaporator to the state of the temperature being 25 DEG C and the moisture content 15 percent or below to obtain an apple pomace product. The technical process can be easily controlled; the production efficiency is high;the production cost is low; the product quality is stable; the problem that the apple pomace coking or non-drying phenomenon can easily occur after the once drying is thoroughly solved; the obtainedapple pomace has the advantage of dampness getting and moisture absorption avoidance.
Description
technical field [0001] The invention belongs to the technical field of feed production, in particular to a method for drying apple pomace. technical background [0002] The dry matter obtained by squeezing or directly drying apples can be used as a raw material in the feed formula to make apple pomace feed for livestock and poultry; the dry matter obtained by squeezing or directly drying apples can be made into feed for livestock and poultry Apple pomace feed additive for poultry feeding. [0003] The existing method for drying apple pomace is completed by one drying technique. The apple pomace is dried once by the drying equipment under high temperature conditions, and the volume filling rate of the apple pomace material in the drying equipment is 30-50%. The process of drying apple pomace at one time does not have a crushing process. Therefore, the drying process is difficult to control, the drying efficiency is low, the production efficiency is low, the product quality ...
