Abstract

FIELD: conservation of velvet antlers of northern deer. SUBSTANCE: velvet antlers ate stepped treated by hot air. The first step takes place within 4 h at 70-72 C, preliminary heating to 68-70 C being carried out. Then wind drying within 48 h takes place. Said cycle is repeated 2-3 times. The second step takes place within 4 h at 65-68 C, stream of hot air being used; velvet antlers are preliminary heated to 65 C. Then wind drying within 48-72 h is carried out. The third step is carried out within 4-10 days with the help of draft till tops of velvet antlers become hard. EFFECT: decreases drying time, improves quality of velvet antlers. 1 tbl

Description

 The invention relates to the primary processing of pharmaceutical raw materials preserving freshly sawn non-ossified reindeer antlers, hereinafter referred to as antlers.

A known method of preserving antlers in the Siberian deer farms, where deer and deer antlers are dried in special easily-bleached rooms at natural temperature. This method does not make it possible to obtain high-quality raw materials from antler reindeer due to the large difference in climatic zones. A known method of cooking antlers of red deer in water at a temperature of 96-98 ^about With subsequent drying under a canopy in gauze rooms in the open air. However, this method reduces the medicinal properties of antlers (leaching of blood), too time-consuming and low productivity.

The closest technical solution is the method of preserving antlers according to the "Technological Schedule" of the NIISH Far North. The method consists in a flame-dried antlers chamber at a temperature of 70-75 ^{° C} for 4 hours followed by treatment in a dryer at a wind vivo. The disadvantage of this method is the low percentage of first-class antlers. Only 15-30% of high quality raw materials.

 The aim of the invention is to increase the yield of first-class raw materials by phased drying of antlers.

This goal is achieved by the fact that in the known method of preserving antlers, which consists in drying the antlers in a heat chamber with subsequent processing in a wind dryer under natural conditions, the antlers are dried in three stages:
First in the flame chamber at a temperature of 70-72 ^{° C} for 4 hours antlers preheating to a temperature of 68-70 ° ^C. Then produce wind forced air drying for 48 hours. The operation is repeated from 1 to 3 times. In the second stage flame drying is carried out at a temperature of 65-68 ^{° C} in the flame chamber for 4 hours antlers preheating to a temperature of 65 ° ^C is then carried out wind drying for 48-72 hours in a forced air room. The third stage, upon reaching the tops of antlers of springy hardness, they are placed on racks in a dry room and dried in a draft at natural temperature for 4-10 days.

To obtain high quality products, the following conditions must be observed:
for drying antlers, MP Sever or MP-85 is used;
until the call from the brigade, the antlers are stored under moss on frozen ground in waterproof containers;
from cut to the final result, antlers are stored only in a horizontal position;
air must be supplied to the room in all directions to ensure intensive uniform heating of the antlers;
the process of heating and cooling should not be more than 6 hours, since the blood in the antlers will begin to blacken production is spoiled.

The proposed method is as follows. In the dryer, equipped in all corners at the top and bottom with thermometers, the antlers are laid out on the grid racks so that they do not touch each other with the top up. Trunk inclination angle the punt should be ^about 15, which is very important. Hot air is supplied into the room through the sleeves using the Sever or MP-85 machine. For its uniform distribution in the room, holes are made in the sleeves. Hot air is continuously blown up until the temperature reaches 70-72 ° ^C. At this temperature, panty maintained for 4 hours. The process should proceed intensively, but without exceeding the temperature of 72 ^{° C,} otherwise antlers can "boil" t ie, their skin will peel off the horn, which will turn yellow and the quality will drop. In addition, there should be a small draft in the room so that moisture-saturated air can escape from the room. After warming up, the room is ventilated with machines without heating continuously for 48 hours. This operation is repeated several times depending on the age and sex groups of animals.

The second stage of drying with hot air antler is carried out at a temperature of 65-68 ^{° C} for 4 hours. Then, drying wind is conducted with open windows, the air pumping machines without heating continuously for 48-72 hours. The air temperature must be 10-15 ° ^C The number of cycles in the second stage is determined by the thickness of the antler. Particularly thick antler deer of the forest zone are dried up to 10 times. After the second stage of drying, the top of the antler should be resilient. Go to the third stage. Antlers are taken out in a dry room for drying on racks at a natural temperature in a draft for 4-10 days.

 PRI me R. According to the proposed method, antlers were dried in the GPP "Surindinsky". In 1990, the state farm "Surindinsky" procured 780 kg of raw antlers from cows, bulls, Tretiaks and gobies for 2 years.

Stage 1
Bulls choruses 3 cycles at 72 ^{° C,} ventilation, drying 48 hours.

TRETYAK 2 cycles at 72 ^{° C,} ventilation, drying 48 hours.

Steers 2 years 1 cycle at 72 ^{° C,} ventilation, drying 48 hours.

2 stage
Mora 7 cycles at a temperature of 65-68 ^about C, ventilation, drying 48 hours

Bulls 5 cycles at a temperature of 65-68 ^о С, ventilation, drying 48 hours.

TRETYAK 3 cycles at 65 ^{° C,} ventilation, drying 48 hours.

Steers 2 s 2 cycles at 65 ^{° C,} ventilation, drying 48 hours.

3 stage
Mora 10 days of wind drying in natural conditions on a draft.

 Bulls 8 days of wind drying in natural conditions on a draft.

 Tretyaki 5 days of wind drying in natural conditions on a draft.

 Gobies 2 years 5 days of wind drying in natural conditions in a draft.

With a yield of 32% in dry form, 247.6 kg of dry antlers were obtained. In the process of transportation to the city of Zabarovsk, it took 2.5 kg or 1.1% to dry, 247.1 kg of antlers were submitted for sorting at the Rantarin joint venture. When sorting, sawing (sawdust) took 1.1 kg. The insurance reserve of 3% was 7.3 kg, the remaining 238.7 kg of antlers were sorted: 1st grade "A" 174 kg or 73.2% 2nd grade "Fi" 4.8 kg or 2.01% 3 grade "C" 59.1 kg or 24.75%
When drying antlers according to the "Technological Schedule" at the state farm "Surindinsky" in 1987 received the following:
A batch of 196.6 kg of dry products. From them by grades: 1st grade "A" 46.7 kg or 25.4% 2nd grade "Fi" 5.7 kg or 3% 3rd grade "C" 49.9 kg or 27%
74.3 kg were unsuitable for consumption.

Using the proposed method provides the following advantages:
the horns of gobies of 2 years and Tretiaks do not deteriorate;
fuel and lubricating oils are saved due to regular inspections and selection of finished products for ventilation;
drying times are reduced due to forced continuous accelerated drying process;
spoilage (decay) of especially thick antlers stops due to the accelerated drying process.
