Abstract
The invention discloses a kind of leech drying means, the following steps are included: leech slurry is placed on the crawler belt continuously moved, the crawler belt successively passes through the first heating zone and the second heating zone of vacuum, first Heating Zone Temperature is set as 70~80 DEG C, and second Heating Zone Temperature is arranged 40~50 DEG C.Energy rapid draing leech of the present invention, and the effective component hirudin of leech can be saved to greatest extent, it is at low cost, drying efficiency is high, improve the leech cellulose content of leech intermediate, to keep Related product hirudin quality higher, and price is lower, has benefited the common people significantly.
Description
Technical field
The present invention relates to a kind of drying means, more particularly to a kind of leech drying means.
Background technique
The main effective ingredient of leech is hirudin, and hirudin can effectively inhibit the activity of fibrin ferment, has anticoagulation, anti-blood
The effects of stimulation of bolt, the proliferation for inhibiting fibrocyte made of thrombin induction and fibrin ferment Human Umbilical Vein Endothelial Cells, thus can be with
Blood-breaking, by the stasis of blood, coronary circulation-promoting pain-relieving, to abdominal mass lump in the abdomen, blood stasis, the illnesss such as traumatic injury have important curative effect.It is clinically main
Treatment for the Acute Cerebral Infarction of blood stasis, convalescence and sequelae.It can also be used for transient ischemic attack, cerebral artery congee
The treatment of the diseases such as sample hardening, vertebrobasilar insufficiency.
The drying mode of leech mainly has fluidized drying, frozen drying at present.Wherein fluidized drying, it usually needs add
Fluidized drying is carried out again after entering the starch wet granulation of 1~1.5 times of leech slurry, and leech cellulose content obtains dilute after addition much starch
It releases, causes the intermediate unit leech cellulose content of manufactured hirudin lower.Frozen drying, advantage be hirudin slightly
Height, but drying time is long, it usually needs drying could be completed within 2 to 3 days, equipment input cost is high, low output, entreprise cost
Height, to increase burden of patients.
Therefore those skilled in the art be dedicated to developing a kind of drying quickly, it is hirudin high income, at low cost, simple and reliable
Leech drying means.
Summary of the invention
In view of the above drawbacks of the prior art, technical problem to be solved by the invention is to provide a kind of dryings quickly,
Hirudin high income, at low cost, simple and reliable leech drying means.
To achieve the above object, the present invention provides a kind of leech drying means, comprising the following steps: is placed in leech slurry
On the crawler belt continuously moved, the crawler belt successively passes through the first heating zone and the second heating zone of vacuum, first heating zone
Temperature setting is 70~80 DEG C, and second Heating Zone Temperature is arranged 40~50 DEG C.
Preferably, the transmission speed of the crawler belt is 0.03~0.1m/min.
Preferably, the vacuum degree of first heating zone and the second heating zone is -100~-80kpa.
Preferably, the time that the crawler belt passes through the first heating zone is 20~45min, the crawler belt passes through the second heating zone
Time be 20~70min
Preferably, it is 0.6~1.5L/H that the leech slurry, which is placed in the charging rate on the crawler belt,.
Preferably, leech length of tissue is no more than 0.5cm in the leech slurry.
The beneficial effects of the present invention are: energy rapid draing leech of the present invention, and can save to greatest extent leech it is effective at
Point hirudin, it is at low cost, drying efficiency is high, the leech cellulose content of leech intermediate is improved, to make Related product hirudin
Quality is higher, and price is lower, has benefited the common people significantly.
