Description
Fig.2
The present invention relates to the field of processing of livestock
and poultry bones, in particular to a crushing device of livestock and
poultry bones and crushing method thereof.
About 12 million tons of edible animal bones are produced each year
in China, which account for about 30% of world's production, can be
converted about 2 million tons of animal proteins, and can meet the
annual protein demand of 75 million people. Livestock and poultry bones
are rich in protein, lipids, minerals and other nutrients, which have high
development value.
Preliminary crushing treatment of the livestock and poultry bones is
very critical when the livestock and poultry bones are processed. The
crushing particle size has a great influence on the processing difficulty
and yield of subsequent processing of the livestock and poultry bones.
Several bone rolling machines are presently used, which all follow
crushers of other non-food industries. However, rolling bone cannot
achieve a crushing evenly purpose when bovine bones, pig bones, and
sheep bones need to be processed because their shape and hardness are
different. Complete crushing is often achieved by increasing the power of a driving motor and strengthening the strength of a cutter. However, such a high-power motor consumes more energy when relatively small and small hardness bones are rolled. High-hardness cutters are easily damaged when high-hardness bones similar to corbel bones are rolled, and other cutters will be damaged by damaged small pieces of the cutter head. Uneven pieces are often obtained by primary crushing with a single crushing equipment, which often need to be performed secondary crushing after picking large pieces, or are achieved uniform crushing and required particle size requirements by adding another crushing equipment, so that crushing, cleaning operations, investment, land occupation, and maintenance are also correspondingly increased.
Therefore, the traditional bone rolling machine cannot satisfy meet the
requirements of the diversity of raw materials and the use reliability, and
