The present invention relates to a continuous automatic vacuum freeze-drying apparatus in which a series of operations are continuously performed from the injection of the extract extract to the powdering of the extract extracted from the flora and fauna of the present invention until it is dried and powdered.

General physical properties of extracts from copper and plants have high viscosity, low freezing temperature, severe foaming during vacuum exhaust, and dried powders are very absorbent (muddy) and sensitive to drying temperature. Sensitively.

By the way, the conventional copper and plant extracting vacuum condensation dryer is usually placed in a tray (TRAY) and dried in a batch type (BATCH TYPE), in the post-drying treatment is often the case that the contact with the atmospheric air is excessively absorbed again in the dried powder. Therefore, there was a lot of unsanitary points, too, and there was a lot of difficulties due to scattering in packing dry powder.

In addition, there is a continuous vacuum freeze dryer, which is continuous by a belt conveyor type, which causes severe scattering of the dry powder, and does not prevent and control the foaming of foam. It was.

Therefore, the present invention aims to provide a continuous automatic vacuum freeze drying apparatus capable of stably powdering any copper or plant extracts by operating stably on the physical properties of copper and plant extracts in order to solve the above problems. It is a double tube connected to a pre-freeze crusher into which copper and plant extracts are injected. The inner hollow part is partitioned into three equal parts to form the first, second and third circulation parts. The first, second and third vacuum dryers installed by the screw rods rotated up and down are arranged up and down, and the extracts are zigzag-connected to be sent out while freezing and sublimation drying, and the freeze-dried powder is dried at the end of the third vacuum dryer. In order to suppress the contact with the atmosphere of the freeze-sublimated powder by installing a collecting mill for collecting and pulverizing the quantitative discharge packing machine.

And, except for the first circulation portion of the first vacuum dryer, the heat medium (hot water) for sublimation of the frozen extract is circulated, and at least one foam defoamer and scattering prevention device are respectively installed in the upper part of the dryer in which the screw rod is installed. Connected to the vacuum device to maintain the vacuum level in the dryer, and connected to the vacuum control means for operating the appropriate vacuum degree as appropriate time on the vacuum pipe, and installed a condenser to collect and condense and drain the sublimated water vapor .

When described in more detail by the accompanying drawings as follows.

In constructing the freeze-vacuum drying apparatus for the extract of copper and plants, the preliminary freeze crusher having an extract inlet 11 and an outlet 12 at one end and a rear end thereof, and having a refrigerant circulation part 13 as a double tube body 1 The inside of the) is a screw rod 14 that is rotated by a motor (M ₁ ) attached to the tip is installed, the lower portion of the structure is larger than the pre-freeze crusher, the partition wall (21) equally divided into a double tube body 1, 2 , The three circulation parts (21a, 21b, 21c) is partitioned therein is a screw rod 24 is rotated by the power of the motor (M ₂ ) attached to the tip is installed, the upper at least one foam defoaming machine 22 The branch has the same structure as the first and second vacuum dryers 2A and 2B and the first and second vacuum dryers, and has a third vacuum dryer 2C having at least one scattering preventer 22b thereon. To the rear end of the first and second vacuum dryers 2A and 2B and to the front end of the second and third vacuum dryers 2B and 2C. Condenser (COLDTRAP) which is connected to the zigzag to transfer the object to be lyophilized, and each of the bubble defoamer and scattering preventers (22a, 22b) condensed and drained the sublimed water vapor in parallel with the vacuum pipe (3) ( 5) is connected to the vacuum device 6 through the vacuum switch (4) having a timer (41) for maintaining the set vacuum degree only for a set time on the vacuum pipe (3) The refrigerant from the freezer (7) is connected to the circulation section (13) between the first circulation section (21a) of the first vacuum dryer (2A) and the double cylinder of the pre-freeze mill (1). The first, second and third circulation parts 21a, 21b and 21c of the second and third vacuum dryers 2B and 2C and the second and third circulation parts 21b and 21c of the first vacuum dryer. The furnace is configured to be connected to the heated hot water for circulating the frozen extract to be collected through the outlet 22 at the rear end of the third vacuum dryer (2C). The wedge 25 and the discharge amount packaging machine 26 is provided.

In addition, it is preferable to coat the heat insulation layer on the outside of the vacuum dryer for thermal efficiency (not shown in the figure the hot water circulator and the heat insulation layer).

On the other hand, the configuration of the foam defoaming machine (22a) is as shown in Figure 3a in the tubular body is located inside the tubular first mesh 101 having a smaller diameter than the upper portion and the lower portion coincides with the inner diameter of the tube body The hatch-shaped second net body 102 and the inlet hatch-type third net 103 which are symmetrically installed at the lower part are laid, and the lower part is smaller than the inner diameter of the body and has a hole 105 'at the bottom. A hatch-shaped first preventive device 105 is provided, and a hatch-shaped second preventive device 106 having a hole 106 'smaller than the size of the first preventive device fixed to the inner diameter of the body is interposed therebetween. to be.

And the scattering preventer (22b) is installed at least one or more fixed to the inner diameter of the body at a certain interval between the upper and lower spatula first prevention device 201 having a hole (201 ') from the top, as shown in Figure 3 (b) The lower portion of each of the lower portion is larger than the hole 201 'and has a bottom structure having a lower structure than the body inner diameter is supported structure is fixed.

In the figure, reference numeral 31 'is an air outlet, 32 is a pressure gauge, 51 is a drain valve, and 7 is a freezer.

Looking at the operating state of the present invention configured as described above the inlet is extracted from the copper, plants in a state of cooling to about -60 ℃ by the freezer (7) to the circulation section 13 of the double tube of preliminary freeze crusher (1) When injected into (11), the first vacuum dryer (2A) through the discharge port 12 is crushed and moved to the right side in the drawing by the screw rod (14) that is rapidly frozen and rotated by the operation of the motor (M ₁ ) The refrigerant is circulated in the first circulation portion 21a so that the refrigerant is circulated, thereby maintaining a state of about −20 ° C. to prevent sublimation. In addition, each of the first, second, and third space parts 21a, 21b, 21c of the second circulation part, the third circulation part 21b, 21c, and the second and third vacuum dryers 2B, 2C has hot water for sublimation. Sublimation occurs from the central part of the first vacuum dryer 2A. At this time, the temperature condition of the drying chamber is about + 30 ° C., and about + 35 ° C. at the rear end is circulated between the zigzag and the temperature is sequentially increased. .

Thus cooling the movement of the frozen extract is a motor (M ₂₎ is freeze-extract to be relatively rotating the second vacuum dryer (2B) there is by means of a screw rod 24 rotated by the motor (M ₂₎ the It is introduced into the second vacuum dryer (2B) through the connecting pipe 23 of the first vacuum dryer (2A) to the front end portion, and is introduced into the third vacuum dryer (2C) through the connecting pipe (23) and transported backward. In this transfer process, the frozen frozen extract is dried as it is sublimed.

Then, it is pulverized in the collection crusher 25 through the rear end outlet 22 and packaged in the quantitative discharge packaging machine 26 to achieve a series of automated systems.

On the other hand, in order to achieve the above action, it is necessary to prevent the generation of bubbles in the first and second vacuum dryers (2A, 2B) and scattering in the third vacuum dryer (2C) and to maintain a vacuum state. Looking at the action to maintain the state as shown in FIG. 1 in the vacuum pipe (3a) and the antifoam 22a and the scattering preventer (22b) located in the upper portion of the vacuum dryer (2A, 2B), respectively, in the state connected in parallel The vacuum is maintained by the vacuum device 6 passing through the condenser 5.

At this time, if the operating time of the timer 41 and the vacuum degree of the vacuum switch 4 are set to maintain the set pressure during the set time, the electronic switching valve 31 is opened when the inside of the vacuum pipe 3 becomes less than the set value. The vacuum switch 4 controls the vacuum switch 4 to maintain the vacuum degree, and the vacuum degree decreases after a set time.

The sublimed water vapor is cooled and thawed in the condenser 5 through the vacuum tube 3 to be drained through the drain valve 51.

At this time, when looking at the action of the bubble defoaming machine (22a), the humidity of the water vapor is very high as the sublimation in the first and second vacuum dryers, bubbles generated by the physical properties of the copper, plant extraction extract, which is the vacuum pipe (3) The large bubble is prevented by the first preventive device 105 and the second preventive device 106 therebetween so that a large bubble is placed above and below the lower part, and the hole 105 'of the lower first preventive device 105 is Destroys a large bubble, and even if a relatively small bubble rises to the inner diameter of the body, the structure prevents the large bubbles from returning between the second prevention device 106 and the inner diameter of the body. 105 finally blocks this relatively large bubble.

Thereafter, since the upper and second hatch-shaped third and second and first hammers 103, 102 and 101 pass through the vacuum tube 3 only in the state of being completely crushed to small bubbles.

In addition, in the third vacuum drying room, the sublimation action is almost completed and the powdered state is to be scattered through the vacuum pipe, but a small amount of powder is scattered through the vacuum pipe. The powder scattered by the edges 202 and the powder scattered to the edges flows into the upper hole 201 'of the hatched first preventive device 201 and is installed in the hatched second preventive device 202 sequentially installed. It acts continuously to prevent scattering.

The present invention constructed and operated as described above is a very useful design that continuously completes a series of operations from sending the extracted copper and plant extract stocks to the pre-freeze crusher to the powdering process. Not only powdering but also the characteristics of the extract, by controlling the temperature and vacuum degree and time of the circulating fruit of the vacuum dryer there is a feature that can obtain a high quality powder in the most suitable vacuum freeze-dried state.
