Antler is an unossified tender horn that grows in the forehead of a male deer. Chinese medicine believes that pilose antler has the role of kidney yang. Modern scientific research shows that antler has a role in regulating the body's metabolism, anti-aging, anti-fatigue and improve the body's immune system, promote gastrointestinal secretion, enhance muscle strength, etc. It is a very precious Chinese herbal medicine. Timely harvesting and processing can directly improve the economic benefits of deer conservation. 1. Preparation before harvesting the antler (1) Organizing specialized personnel Professionally supporting the deer farm The velvet group should be composed of experienced processing personnel. The growth status of the velvet in the field should be observed every day in order to timely harvest the velvet. (2) Fields (households) that have equipment and articles ready for harvesting using the mechanical Baoding method should conduct a complete overhaul of semi-automatic splint-type stabilizers (hanging rings) and prepare saw-saw saws, anesthetics, and hemostatic drugs. The equipment needed to process antler. (3) Grasp the timing of velveteen velvet Accurate timing should be determined according to the needs of the market. At the same time, the output of pilose antler should also be considered. When the sika deer saws, it takes two twigs to collect the antler, and two saws generally receive two antlers. If the sika deer saw can produce two sticks of antler weighing more than 0.5kg, the two saws can take in three pods. The male deer with more than three saws mainly receives trifoliate. Red deer generally do not accept horse lotus antler (equivalent to two deer sika deer), mainly to receive three pods of antler, for individual growth is good, growing strong velvet can consider four pods antler. When harvesting the antler, observe the velvet's mouth and roots. If the mouth of the velvet is thick and plump, the growth is strong and the velvety root does not show the cucumber diced and squash rind shape, you may consider collecting the velvet antler, but on the contrary you should receive the small velvet antler. 2. Baoding deer's Baoding method mainly includes mechanical Baoding and drug Baoding. The combination of mechanical Baoding and drug Baoding is rare in practical applications. (1) Mechanical Baoding Machinery The main instrument of Baoding is a semi-automatic plywood stabilizer (hanging ring), which is formed by a channel that communicates with the pens and the stabilizer. There are multiple doors in the channel and there are disc-type turnstiles. When the deer enters the channel, the deer to be sawed can be pushed into the Baoding device to give Baoding. (2) The drug Baoding mainly uses anesthetic drugs to anesthetize the deer, making the deer to be sawn in a coma and achieve the purpose of Baoding. Commonly used anesthetic drugs mainly include two kinds of scopolamine and metonitin. 3. Saw-wing Velvet Technology (1) The time is due to the midsummer of the whole velvet season, and the temperature is high. It is advisable to feed the saw velvet before the early morning feeding. Because at this time the deer fasting, the environment is quiet, easy to restore the physical strength of saw-furrow deer and post-saw velvet processing, anti-corrosion, drying treatment. (2) After the site of deer Baoding, use a special velvet saw to saw it on the upper side of the pearl plate 1.5cm to 2cm. Saw mouth plane parallel to the pearl plate, do not damage the corner base, so as not to destroy the velvet foundation. The sawed antler is weighed and registered and sent to the processing room for processing. (3) Hemostatic drugs commonly used for hemostasis are Qiqi San and zinc chloride, which are mixed and ground into powder. The kiln powder and the loess are dried and ground into a powder and used as a spare. Divided into several pieces and placed on a thick piece of paper. After sawing the velvet, place a thick piece of paper on the hand and press the medicine on the kerf to press the medicine evenly. Saw on the mouth. When the individual deer bleeds severely, the hemostatic agent can be pressed evenly at the kerf, and the small plastic cloth covering the kerf can be ligated with a straw rope to stop bleeding at the corner base. The plastic cloth and the fine straw rope can be removed within 24 hours to prevent the time from becoming too long. And make the keratin necrosis, lose antler ability. After the saw-swept antler was over, the deer secured by the mechanical method of Baoding was released and the Baoding device was released so that the deer could be released. Injecting Dekling anesthetized can naturally awaken it. Injecting anesthetized mimononin can be used to wake up the spirit, but also allow it to naturally wake up. 4. New processing technology Antler is an expensive Chinese herbal medicine. Its ingredients are very complex, it is difficult to dry, and it is easy to change rancid. For a long time, China has been using boiling water and high-temperature baking combined with the process, the fresh antler processing into dry products. This processing method has a long working time, labor intensity, and low production efficiency, and can easily lead to a large number of loss and destruction of active ingredients and active substances in the velvet antler, resulting in phenomena such as peeling, shorting, rancidity, coking, and spoilage (dysmeric). Affects efficacy. In order to surpass the traditional processing methods, reduce nutrient loss, reduce energy consumption, and improve the competitiveness of China's antler and its by-products in the international market, researchers have used modern microwave technology, far-infrared technology, and electronic technology to research and develop applications. New technology and new equipment for processing velvet velvet. Compared with traditional processing methods, the loss of nutrient components in velvet is reduced by 4%, and the velvet and stinky antler are reduced by 5%. The processing is full of velvet, and the velvet is full and full of blood. , The active substance in the antler is fresh and odor-free. (1) Microwave and Far-Infrared Ray Processing of Antler Technology Process 1 Equipment. The supporting equipment for this new technology includes refrigerators, microwave equipment (including microwave power generators and microwave ovens), smelting equipment, far infrared drying boxes, and blowers. 2 processing arts. Fresh velvet → Draining blood (with blood velvet seal sawing) → Scrubbing decontamination → Microwave heating leaves Boiled antler skin → Hair cold → Far infrared and microwave energy heating and drying → Backwater → Boil the head → Finished velvet. The fried pilose antler is subjected to microwave heating. Batch processing can be processed each time fresh velvet 10kg ~ 15kg (water content of more than 60%), or semi-dried 20kg ~ 25kg (water content of about 20% ~ 30%). Microwave oven power is 1.6kW ~ 3.0kW, heating 3 to 5 times, each takes 2min ~ 3min, cool time after each heating is 3 times to 5 times the heating time. When cold, open the door of the microwave oven. (2) Freeze-Drying Technology 1 Boiling. The pilose antler was boiled once before vacuum freezing in the same manner as in the first boiling water boiling of conventional processing. 2 freeze-dried. First, the antler was quickly frozen (drying chamber temperature is -30 °C ~ 25 °C) 2h, and then start the condenser (at a temperature of -28 °C) cooling 30min; start the vacuum pump shovel after 5min box cooling can be completed (this time the vacuum Degrees of up to 400 Pa ~ 533 Pa), while the condenser continues to cool -45 °C ~ 39 °C. 3 heat treatment. After the cooling of the box is stopped, the heating is performed using a heating device (the temperature of the inside of the box is 1 h, preferably 10° C.) to 60° C., and the drying time is approximately 20 h to 25 h. Two twigs of flower twigs are warmed up at a temperature of about 20°C for 1 h, heated to 65°C, and dried for 18 h to 20 h. (3) Dual electronic automatic control far infrared drying box processing technology 1 equipment. The new technology is equipped with dual-electronic automatic control far-infrared drying box and electronic automatic temperature sterilizer. 2 processing technology. Fresh Velvet → Draining blood (with bloody seal kerf) → Scrub velvet skin → Using electronic constant temperature broiler frying → Cooling → Dual electron far infrared drying → Air drying → Backwater → Dual electron far infrared drying hopper Drying →Boiled head → finished product velvet. When processing bloody velvet, generally take 20 to 40 velvet with the same specifications, the first three baking temperatures of 75 °C, baking time of 120min ~ 180min, 1 in the morning and 1 in the afternoon, timely return water, Cool; after the 4th return, the baking temperature is 75°C, the baking time is about 120 minutes, and the morning and afternoon are also 1 time, and the water is cool and cold in the second. When the processing row of blood velvet, baking temperature is 70 °C, each baking time is 45min ~ 60min. The drying box has automatic temperature control, timing, and alarm. It has good moisture-discharging performance and is easy to operate. It can improve the quality of pilose antler processing products and can automatically cool the air when it encounters faults.
