Description

An apparatus for concentrating sap}

One embodiment of the present invention relates to a liquid concentrator for separating treated water from liquid and concentrating the liquid.

It is the osmotic phenomenon that the low concentration solution moves to the high concentration due to natural diffusion phenomenon when the high concentration solution is put on one side of the permeation membrane which is isolated by the semipermeable membrane and the low concentration solution is put on the other side. .

However, when a pressure higher than osmotic pressure is applied to a high concentration solution, the reverse osmosis phenomenon occurs, and the reverse osmosis phenomenon is called reverse osmosis.

The reverse osmosis filter is a device that purifies water by passing only water molecules through a semi-permeable membrane using this membrane. Since the reverse osmosis filter filters more than 99% of various contaminants such as bacteria and viruses, only pure water molecules pass through it.

In general, the reverse osmotic pressure system is used for purifying pure water to be used for drinking, and pure water is taken and the remainder is discarded. In the present invention, pure water is removed by reverse osmosis, and components such as sugar and minerals And to provide a liquid concentrator capable of concentrating the liquid.

The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

1 is a perspective view of a liquid concentrating apparatus 100A, 100B according to an embodiment of the present invention.

The liquid concentration apparatuses 100A and 100B may be configured such that pumps and filters are built in the housing 106. [ The housing 106 may be a polyhedron, and the material thereof may be stainless steel.

A fluid supply pressure gauge 101, a high-pressure pump pressure gauge 102, a concentrated water flow meter 103, a treated water flow meter 104 and a switch unit 105 are disposed on one surface of the housing 106 so that the user can pressurize the pressure gauges and flow meters It is possible to manually adjust the liquid concentration apparatuses 100A and 100B manually.

The fluid supply pressure gauge 101 is connected to the first pump 130 (see FIG. 2) and is capable of measuring the pressure of the fluid supplied to the settling filter 110 (see FIG. 2) through the first pump 130 .

The high pressure pump pressure gauge 102 is connected to the second pump 140 (see FIG. 2) and measures the pressure of the filtered water supplied to the reverse osmosis membrane filter 120 (see FIG. 2) through the second pump 140 .

The concentrated water flow meter 103 is configured to confirm the flow rate of the concentrated water discharged from the reverse osmosis membrane filter 120 (see FIG. 2), and the treated water flow meter 104 is connected to the reverse osmosis membrane filter 120 The flow rate of the fluid is determined.

The switch unit 105 is composed of a plurality of switches, so that the operation of each pump and each valve can be controlled manually. In addition, as described later, the controller 108 can be set through a switch so that each of the pumps and each of the valves is automatically operated.

A control unit 108 is disposed inside the housing 106 in the form of a microcomputer and is set such that the control unit 108 can automatically control the operation of each pump and each valve through the switch unit 105.

2 is a conceptual diagram of the liquid concentrator 100A related to the first embodiment of the present invention.

2, the liquid concentration apparatus 100A includes a settling filter 110, a reverse osmosis membrane filter 120, a first pump 130, a second pump 140, and a flow control unit 180 .

The sedimentation filter 110 is formed to receive the filtrate and discharge the filtrate. The sedimentation filter 110 filters the particulate matter from the liquid as well as chlorine or volatile organic chemicals. The settling filter 110 first introduces a liquid such as a corn tree sap, and generally filters up to 10 micrometers or more of debris and contaminants, usually contained in the liquid, so that the components of the subsequent process can operate normally, Is treated with high-temperature carbon, so that chlorine component, trihalomethane (THM) and volatile organic chemical dissolved in the liquid can be adsorbed and removed. This protects the reverse osmosis membrane filter 120 and ensures normal functioning.

Depending on the filtration ability of the filter, the amount of fibers contained in the filtrate after filtration may vary. In addition, resin filters, various functional filters, and the like for purifying pure water also purify impurities at an ionic level. Therefore, components such as various minerals, iron powders, sugar and other edible fibers contained in liquid for edible purposes are also filtered There is a risk that the nutrients as the edible liquid may be removed. In addition, when a filtration filter having a high filtration ability is used, components contained in the filtrate are precipitated on the inner wall of the filtration apparatus during the purification of a large amount of fluid, so that the filtration rate is rapidly lowered, and the replacement cycle of the filter is extremely shortened Which is economically disadvantageous. Therefore, the sedimentation filter used in the present invention was intended to maintain a level at which no variation occurs in the nutritional components by using a filter capable of filtering to molecules of 0.1 m or more. The filtration filter is not limited to the material and the kind thereof, but a filtration type filter, an exchange type filtration filter, a purification filter for purification and the like can be used.

In the sedimentation filter 110, the liquid is introduced into one side through the first pump 130, and the filtered water is discharged to the other side.

The reverse osmosis membrane filter 120 discharges treated water, which is mostly water, out of the filtered water to the first outlet 121, and discharges the concentrated water in which the sugar and minerals are concentrated in the filtered water to the second outlet 122. At this time, the filtered water is boosted by the second pump 140 so that the reverse osmosis can be performed.

The second pump 140 supplies the filtered water to the reverse osmosis membrane filter 120 at a pressure higher than that of the first pump 130. In order to prevent the filtered water from flowing back toward the settling filter 110, A check valve may be disposed between the pump 140 and the settling filter 110.

The concentrated water discharged through the second outlet 122 may be recondensed through the circulation line 170. To this end, a first three-way valve 150 and a second three-way valve 160 are disposed on both sides of the circulation line 170, respectively.

The control unit 108 can move the concentrated water toward the second three-way valve 160 through the first three-way valve 150 and the circulation line 170 by adjusting the three-way valves so that the concentrated water is re- 2 pump 140 can be operated.

At least one sterilizer 190 may be disposed between the settling filter 110 and the reverse osmosis membrane filter 120. The sterilizer 190 is a device for sterilizing microorganisms and harmful bacteria remaining in the liquid and purifying the microorganisms and harmful microorganisms to a level that can be consumed for drinking. Due to the characteristics of edible liquids, when heat treatment is performed at a high temperature, the dietary fiber contained in the liquid precipitates and the nutrients are destroyed and deformed, so that it is difficult to carry out the sterilization treatment by the high temperature heating method. Therefore, in the present invention, the sanitary fluid can be supplied by removing the harmful bacteria using the pasteurizer 190. Although the kind of the paste sterilizer 190 is not limited, an ultraviolet sterilizer, a water purifier UV sterilizer, a low temperature heating sterilizer, or the like can be used.

The flow rate regulator 180 regulates the sugar content of the concentrated water. That is, the flow rate of the treated water or the concentrated water discharged through the outlets is controlled. As a result, the sugar content of the concentrated water can be increased.

The operation of the liquid concentrator 100A related to the first embodiment of the present invention is as follows.

First, when the liquid is supplied, the liquid is introduced into the sedimentation filter 110 through the first pump 130. The sap flowing into the sedimentation filter 110 undergoes a filtration action, and the filtered water flows into the second pump 140. The second pump 140 boosts the filtered water and supplies the filtered water to the reverse osmosis membrane filter 120 through the pasteurizer 190. The pasteurizer 190 may be formed in front of the second pump. That is, the filtrate introduced into the sedimentation filter 110 may be boosted by the second pump 140 after passing through the paste-sterilizer 190.

The filtered water flowing into the second reverse osmosis membrane filter 120 is filtered again. In the filtration process, it is separated into treated water and concentrated water, and moves along the piping. The treated water is discharged through the first outlet 121, and the concentrated water moves along the second outlet 122. At this time, the flow rate regulator 180 regulates the flow rate of the treated water discharged through the first discharge port 121 and the concentrated water discharged through the second discharge port 122. As a result, the sugar content of the concentrated water can be controlled. Increasing the amount of effluent water will increase the sugar content of the concentrated water, and reducing the amount of effluent water will lower the sugar content of the concentrated water.

The concentrated water may undergo a re-condensation process, in which case the first three-way valve 150 diverts the concentrated water to the circulation line 170. The concentrated water flowing into the circulation line 170 is re-introduced into the second pump 140 by the second three-way valve 160.

At this time, the second three-way valve 160 can block the filtered water from flowing into the second pump 140. In addition, filtration water and concentrated water can be mixed and supplied to the second pump 140 without blocking the inflow of the filtered water into the second pump 140. If the water escapes excessively during the concentration process, the concentration increases and the reverse osmosis efficiency decreases.

Through the above process, the liquid can be concentrated.

3 is a conceptual diagram of the liquid concentrating apparatus 100B according to the second embodiment of the present invention.

As described above, the sedimentation filter 110 is formed to receive the filtrate and discharge the filtrate. In the sedimentation filter 110, the liquid is introduced into one side through the first pump 130, and the filtered water is discharged to the other side.

The concentrated water discharged through the second outlet 122 may be recondensed through the circulation line 170. For this purpose, a three-way valve 151 and a four-way valve 161 are disposed on both sides of the circulation line 170, respectively.

The control unit 108 adjusts the three-way valve 151 and the four-way valve 161 so that the concentrated water is moved toward the four-way valve 161 through the three-way valve 151 and the circulation line 170 And the second pump 140 can be operated. In addition, to clean the interior of the reverse osmosis membrane filter 120, valves may be opened and closed and the pumps may be operated. For example, one side 162 of the four-way valve 161 is opened and the second pump 140 is operated to allow the foreign substances accumulated on the surface of the membrane to be instantaneously discharged.

The operation of the liquid concentration apparatus 100B according to the second embodiment of the present invention is as follows.

The filtered water flowing into the second reverse osmosis membrane filter 120 is filtered again. In the filtration process, it is separated into treated water and concentrated water, and moves along the piping. The treated water is discharged through the first outlet 121, and the concentrated water moves along the second outlet 122. At this time, the flow rate regulator 180 regulates the flow rate of the treated water discharged through the first discharge port 121 and the concentrated water discharged through the second discharge port 122. As a result, the sugar content of the concentrated water can be controlled. Increasing the amount of effluent water will increase the sugar content of the concentrated water, and reducing the amount of effluent water will lower the sugar content of the concentrated water. The concentrated water may undergo a re-condensation process, in which case the three-way valve 151 diverts the concentrate water to the circulation line 170. The concentrated water flowing into the circulation line 170 is re-introduced into the second pump 140 by the four-way valve 161.

At this time, the four-way valve 161 can prevent the filtered water from flowing into the second pump 140. In addition, filtration water and concentrated water can be mixed and supplied to the second pump 140 without blocking the inflow of the filtered water into the second pump 140. If the water escapes excessively during the concentration process, the concentration increases and the reverse osmosis efficiency decreases.

Through the above process, the liquid can be concentrated.

The use of the liquid concentration apparatuses 100A and 100B according to the present invention has the following advantages.

When syrups are made using sap, especially sap of high citron, they are usually concentrated by heating in the process of concentrating to high sugar. At this time, the amount of fuel used for heating takes a large portion in the production cost, which can be saved to a great extent. That is, production cost reduction and productivity of syrup production can be improved.

In addition, it is possible to reduce the transportation cost of transferring the concentrate to a high concentration syrup production facility after concentrating at a low concentration using reverse osmotic pressure machine rather than transferring the raw liquid to produce syrup.

Concentration of corn syrup liquid by reverse osmosis concentrating method can result in a general sugar content of 1.5 ~ 2.5 brix, which can improve sugar content about twice as much as re-concentration.

In addition, the sugar content of the concentrated water can be more effectively controlled by using the flow rate regulator 180.

The above-described liquid concentration apparatus can be applied to a configuration and a method of the above-described embodiments in a limited manner, but the embodiments can be modified so that all or some of the embodiments are selectively combined .
