And a nitrogen controller that controls the operation of the injection device.

In addition, it is preferable to further include a supplemental water tank for water replenishment connected to the bath.

In addition, it is preferable that a plurality of cooling fans are installed.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a vacuum powder manufacturing apparatus of the food according to the present invention, Figure 2 is a perspective view of a drying tank according to the present invention.

Here, the food means a large amount of water, such as herbal medicine, fruit, food, etc. The present invention is a device for manufacturing a powder by removing the moisture of the food containing a lot of water, depending on the degree of moisture It is also possible to produce a highly concentrated semi-solid material in the form of a gel.

Vacuum powder manufacturing apparatus for food according to an embodiment of the present invention is a drying tank 12 of about 5000cc capacity that can accommodate a concentration of about 2000cc capacity, and about 20,000cc to heat the drying tank 12 in a bath A cooling system composed of a capacity hot tub 11, an electric heater 14 for heating the hot tub 11, a cooling fan 17 and a radiator 16 for cooling water vapor generated during heating; A water storage tank 18 for storing water generated by cooling water vapor, a vacuum control system including a vacuum pump 15 and a vacuum controller 7 for maintaining the drying tank 12 in a vacuum, and a drying tank ( A temperature controller 2 for controlling the temperature of 12), a nitrogen injection device 10 for injecting nitrogen into the drying tank 12, and a nitrogen controller 9 for controlling the operation of the nitrogen injection device 10. It is configured by. A replenishment water tank 4 for replenishing water for replenishing water evaporated from the hot water bath 11 to the atmosphere is connected to the hot water bath 11.

The copper plate 13 is installed on the heater 14 so that the bottom temperature of the drying tank 12 is uniform so that the liquid substance does not burn or depress.

The device does not require a separate water-cooled cooling water supply tank. The cooling fan 17 of the cooling system is installed in a sufficient number in consideration of the capacity of the steam discharged per hour to sufficiently cool the steam in the drying tank 12 generated by indirect heating, the cooling fan 17 and each cooling The capacity of the radiator 16 corresponding to the fan 17 is precisely calculated in order to precisely cool the water vapor discharged per hour, and a large number is attached along the circumference of the device under the drying tank 12 in small capacity as required. In the present embodiment, four cooling fans 17 are installed, but 10 or more cooling fans 17 may be installed.

Initially, the bath is heated at a low temperature of about 50-70 ° C., so there is almost no foaming, and even in the case of a weak substance, there is almost no loss of components and a separate foam recovery device is unnecessary.

The vacuum controller 7 automatically controls the vacuum pump 15 to be operated or stopped at any time according to a program so as to maintain a constant degree of vacuum at all times, and a cooling system is attached around the lower appliance of the water bath 11 and is located therein. Vacuum pump 15 and the reservoir 18 is located at the bottom is designed to utilize the space as appropriate and efficient as possible.

As shown in FIG. 2, the drying tank 12 has lids 23 and 25 on both sides of the upper and lower sides so that the drying tank 12 can be easily opened and closed. The discharge tube 20 and the vacuum check tube 22 which can easily determine the vacuum state are attached to the tube, and the upper lid 23 is made of high-strength transparent tempered glass so that the powder is in progress. It is convenient to check at any time. In addition, the body of the drying tank 12 is made of stainless steel capable of withstanding sufficient vacuum pressure.

Nitrogen is injected by the nitrogen injection device 10 connected to the nitrogen controller 9 which is constantly programmed after the food in the drying tank 12 is dried to some extent, that is, 50 to 60% of the drying is performed.

The nitrogen injection device 10 is a device for further increasing the rate of progress of powdering by the removal of water forcibly due to the continuous heating and vacuum in the interior of the drying tank 12. This is because when the gas is injected into the drying tank 12 while the device is in operation, the harmony of the saturated vacuum state is momentarily broken, and at this time, the instantaneous discharge of the moisture contained in the drying tank 12 is achieved. The principle is to go faster. At this time, the gas to be injected may be air in the atmosphere, which is unsanitary and inefficient because it contains pollutants and some moisture, and may inject oxygen, but in this case, there is a risk of corruption or oxidation. have. Therefore, it is to inject nitrogen that is harmless to the human body. Nitrogen injection does not need to be done at the beginning of the operation, and injection of 1 ~ 2 seconds at intervals of about 5 ~ 20 minutes is an appropriate amount calculated through experimental values.

The reservoir 18 is located below the cooling fan 17 and the vacuum pump 15, i.e., at the bottom of the apparatus, and is provided with a water gauge so that the amount can be observed from the outside. It has a capacity to accommodate more than the maximum amount of coolant that can be discharged from the maximum amount that can be put in. Clear water in the reservoir 12 is discharged in a vacuum released state after the process is completed.

Due to various differences depending on the type of food, density and water content, it is not possible to define the time required for food powdering uniformly, but it is about 300 ~ 500cc per hour based on general Chinese medicine, that is, about one powder of Chinese medicine It can be expected to take three hours.

Referring to the process of powdering food, such as herbal medicines using the vacuum powder manufacturing apparatus of the food according to the present embodiment configured as described above are as follows.

As a first step, the rubber packing 24 is inserted into the lower part of the cylindrical drying tank 12, the circular stainless steel lid 25 is covered, and then joined with a clamp 26 made of stainless steel.

As a second step, food containing up to about 2000 cc of water is introduced into the drying tank 12 through the drying tank 12.

As a third step, the rubber packing 24 is installed on the drying tank 12 and the upper lid 23 made of a transparent tempered glass plate is covered. Then, the clip connected to the water storage tank 18 is coupled.

As a fourth step, the drying bath 12 is put down in the middle bath 11 containing about 1/3 of water, and the temperature controller 2 is operated on to heat the water in the bath. At this time, the drying tank 12 in the water bath 11 is indirectly heated.

As a fifth step, all valves are closed and then the vacuum system connected to the reservoir 18 is started. This vacuum system is set and controlled in advance to maintain a constant pressure.

As a sixth step, the drying dryer 12 connected to the reservoir 18 communicating with the vacuum pump 15 is sealed off from the outside due to the vacuum system and immediately becomes a vacuum state. ) Can be judged easily by looking at the tightening state.

As a sixth step, both the bath bath 11 and the supplemental water tank 4 connected thereto are opened. In this way, the water bath 11 is automatically supplied with water for the bath by the ball tower 5 adjusted as necessary.

As a seventh step, the warm water bath 11 initially heats to a relatively low temperature of about 50 ° C. and observes the inside of the drying tank 12 through the upper lid 23 of the drying tank 12 to dry the drying tank 12. The various reactions inherent in the food inside and adjust the temperature of the heater 14 to a maximum of 80 ~ 95 ℃ within the range that the bubble does not over.

As an eighth step, about 2 hours after the operation of the device, nitrogen is injected for 1 to 2 seconds at intervals of 5 to 20 minutes to accelerate drying. Nitrogen is a harmless gas, which accounts for about 70% of the atmosphere, and when a nitrogen is injected, a certain amount of moisture evaporates, greatly saving the drying time.

As a ninth step, drying depends on the viscosity of the food in the drying tank 12 but takes about three hours per ash, and when the drying is complete, shuts down the heaters 14 and the vacuum system and closes all valves. Then, after confirming that the vacuum confirmation tube 22 is loosened, the drying tank 12 is taken out of the hot water bath 11. Then open the vacuum valve to release the vacuum and then open both lids (23, 25) to collect the produced powder.

As a tenth step, after the vacuum of the reservoir 18 is released, all of the powder manufacturing processes in one cycle are completed by opening the discharge valve to discharge transparent distilled water.

As described above, the present invention has been described only with respect to specific examples, but it is apparent to those skilled in the art that various modifications and changes can be made within the technical spirit of the present invention based on the specific examples above. Of course, it belongs to the utility model registration claim attached to the modification.

As described above, the vacuum powder manufacturing apparatus of the food according to the present invention is all products that need to be dried, that is, herbal medicine. It is a useful device that can be easily used by small companies dealing with black goats, infusions, fruit juices, etc., and its design is optimized so that unnecessary or complicated processes can be omitted, and the configuration of the device is simple, inexpensive, and small. By adopting automatic temperature and vacuum control controller, bubbles are not overflowed, which eliminates the need for a bubble recovery device, reducing the volume of the device, and efficiently producing high purity powders with purity of 95% or more in the shortest time without loss of ingredients. Heating in this way has the advantage that there is no fear of depressing or demineralizing the material in the dryer. By adopting this, a food company or a Korean clinic can produce high-purity specialized powders on a small scale, thereby achieving a small amount of dosage, or approaching various secondary formulations such as capsules and tablets.
