In the case of such a stirring mixing reaction, a general chemical catalyst (acid catalyst, an alkali catalyst) or an immobilized enzyme (biocatalyst) is mainly used for the fat decomposition of the target oils and fats. In the case of the chemical catalyst, And various processes using biocatalyst are being developed recently.

However, in the biodiesel manufacturing process using the biocatalyst, the surface modification of the biocatalyst (immobilized enzyme) is broken and denatured due to the external impact due to the agitation process, resulting in the degradation of the activity of the enzyme, The biodiesel conversion efficiency can not be sufficiently achieved and the expensive immobilized enzyme can not be reused.

In order to solve this problem, the technology disclosed in Korean Patent Publication No. 2015-0014699 is to combine an enzyme trap with a stirring rotary shaft to protect the immobilized enzyme injected into the reactor from an external impact and to fill the trap with an enzyme . The outer surface of the enzyme trap is composed of a mesh network, and the oil in the reactor is allowed to flow through the enzyme trap through the mesh network, so that the activity of the enzyme can be maintained and reused stably .

However, according to this patent document, when the enzyme trap is rotated, the peripheral oil flows along the enzyme trap due to its high viscosity, and thus, it is difficult to smoothly contact the oil and the enzyme. Therefore, it is difficult to expect a high production efficiency by such a technology.

The outer jacket portion 100B is disposed so as to surround the container main body portion 100A. The lower end of the outer jacket portion 100B is provided with an inlet 141 through which temperature control water (hereinafter referred to as a temperature control water) flows and an outlet 142 through which the temperature control water is discharged. The temperature control water may be hot water or cold water.

The thermostatic water flows into the outer jacket portion 100B through the inlet 141 and circulates through the chamber therein and is discharged through the outlet 142 out of the outer jacket portion 100B. Heat exchange with the container body portion 100A occurs, so that the temperature in the container body portion 100A can be adjusted to a temperature suitable for biodiesel generation reaction.

A check window 130 is provided on the outer jacket portion 100B.

The confirmation window 130 allows the user to visually confirm the situation inside the reaction vessel 100.

The confirmation window 130 may desirably be detachable from the reaction vessel 100.

The reaction vessel 100 is provided with three fastening mechanisms 160. This is for fastening between the reaction vessel 100 and a head unit 210 described later.

As shown in FIG. 3, the biodiesel manufacturing apparatus 1 includes a head portion 210.

The head part 210 is formed in a disc shape as a whole, and a handle part 260 is formed on the upper surface.

The head portion 210 is provided with a first through hole 214 and a second through hole 215 penetrating the head portion 210 up and down, respectively.

The first elevating member 241 is slidably inserted into the first through hole 214 and the second elevating member 242 is slidably inserted into the second through hole 215. The first and second elevating members 241 and 242 may be each formed into a long rod shape.

Three second fastening grooves 211 are formed at the edges of the head part 210 at positions corresponding to the three first fastening grooves 111 (see FIG. 2).

Each of the fastening mechanisms 160 is inserted into the corresponding first and second fastening grooves 111 and 211 so that the reaction vessel 100 and the head part 210 are fixed to each other.

A third through hole 216 is formed through the center of the head portion 210 so as to pass through the top and bottom.

The rotating screw 220 is rotatably inserted into the third through hole 216.

A driving motor 300 is installed on the head unit 210 and the rotating screw 220 inserted in the third through hole 216 is rotated by the driving motor 300.

The rotating screw 220 has threads formed on the outer circumferential surface thereof.

The stirring vane 250 is provided under the rotating screw 220. The number of the stirring blades 250 may be increased or decreased as much as possible and any shape of the stirring vane 250 considering the stirring efficiency may be modified It will be possible.

The stirring wing 250 stirs the fluid (biodiesel raw material) accommodated in the container main body 100A to enable the biodiesel generating reaction to be performed more smoothly.

3 to 5, the biodiesel manufacturing apparatus 1 includes an enzyme trap 230. [

The enzyme trap 230 is mounted on the above-described rotating screw 220 so as to be able to move up and down within the container main body 100A. In the enzyme trap 230, a lipase is accommodated. By way of example, the lipolytic enzyme may be a lipase.

The lipolytic enzyme in the enzyme trap 230 serves as a catalyst so that the oil in the container body portion 100A can be decomposed into fatty acid and glycerol. The degraded fatty acid is combined with alcohol to produce FAAE (Fatty Acid Alkyl Eester) corresponding to biodiesel.

The enzyme trap 230 has a first coupling hole 235 at one side and a second coupling hole 236 at the other side.

The first elevating member 241 is inserted and fixed in the first coupling hole 235 and the second elevating member 242 is inserted and fixed in the second coupling hole 236.

The enzyme trap 230 is provided in a circular column shape having a low overall height and includes an upper mesh network 233 and a lower mesh network 234 arranged to face each other.

The fluid in the container body portion 100A can pass through the enzyme trap 230 through the upper mesh network 233 and the lower mesh network 234 and the lipase in the enzyme trap 230 And can perform a catalytic action on the passing fluid.

On the other hand, a screw coupling member 231 is provided at the center of the lower mesh net 234 of the cartridge unit 230.

A screw thread is formed on the inner circumferential surface of the screw coupling member 231 so that the screw coupling member 231 is screwed with a screw thread formed on the outer circumferential surface of the rotating screw 220 described above.

The side part 232 is a part forming the side wall of the enzyme trap 230. As an example, the side portion 232 can be made of an acrylic plate. The side surface portion 232 is disposed adjacent to the inner wall of the container body portion 100A in the container body portion 100A but a gap is formed between the side surface portion 232 and the container body portion 100A do.

In other words, it may be preferable that the diameter of the enzyme trap 230 is formed to be slightly smaller than the inner diameter of the container body portion 100A.

The first elevating member 241 is fixed to the first engaging hole 235 and the second elevating member 242 is engaged with the second engaging hole 235. [ 236, respectively.

Therefore, when the driving motor 300 rotates the rotating screw 220, the enzyme trap 230 can be raised toward the head part 210 or vice versa depending on the rotating direction.

It will be understood that the rotation of the enzyme trap 230 itself can be suppressed at this time.

In the enzyme trap 230, the upper mesh network 233 can be separated if necessary, so that the upper mesh network 233 can be separated and the lipase can be filled in the enzyme trap 230.

On the other hand, it is necessary to set a rising limit point (highest height) and a lowering limit point (lowest height) when the enzyme trap 230 ascends and descends by the operation of the driving motor 300.

To this end, the head unit 210 may further include a sensor unit 400.

The sensor unit 400 senses the position of the upper portion 243 of the first elevating member 241 or the second elevating member 242 that is lifted together when the enzyme trap 230 is lifted.

More specifically, the sensor unit 400 may include an upper sensor (first sensor) 410 and a lower sensor (second sensor) 420 disposed at a height corresponding to a rising limit point .

The upper end 243 of at least one of the first and second lifting members 241 and 242 is lifted when the driving force of the driving motor 300 rises in the first direction and reaches the rising limit point Is sensed by an upper sensor (first sensor) 410.

3) receives the sensing signal of the first sensor 410, the control unit 500 reverses the rotation direction of the driving motor 300 and rotates in the second direction opposite to the first direction.

The enzyme trap 230 starts to descend as it rotates in the second direction of the driving motor 300 and then reaches at the lower limit point (the lowest one), at least one of the first and second lift members 241 and 242 The upper end portion 243 of the second sensor 420 is sensed by the lower sensor (second sensor) 420.

3) receives the sensing signal of the second sensor 420, the control unit 500 reverses the rotation direction of the driving motor 300 to rotate in the first direction. As a result, the enzyme trap 230 is again moved upward.

In this way, the enzyme trap 230 repeats reciprocating motion up and down between the rising limit point (highest height) and the lowering limit point (lowest height) in the reaction vessel 100 during the biodiesel production reaction.

It should be noted that the first and second elevating members 241 and 242 are coupled to the edge of the enzyme trap 230 so that they can move up and down but do not rotate. That is, as the rotary shaft 220 rotates in both directions by the drive motor 300, the enzyme trap 230 does not rotate due to the restraint of the first and second lifting members 241 and 242 .

If the enzyme trap 230 is rotationally driven in the reaction vessel 100, the high viscosity of the oil (raw material of the biodiesel) in the reaction vessel 100 causes a considerable load for its rotational driving, Is consumed.

However, according to the embodiment of the present invention, since the enzyme trap 230 does not rotate but linearly reciprocates up and down, it is possible to minimize the load due to the driving of the enzyme trap 230, and accordingly the power consumption can be minimized .

In addition, during the up / down movement of the enzyme trap 230, the fuel (biodiesel raw material) in the reaction vessel 100 passes through the enzyme trap 230, so that it can sufficiently receive the catalytic action of the enzyme inside the enzyme trap 230.

At this time, the stirring blade 250 installed on the rotating shaft 220 rotates together with the rotating shaft 220 to stir the reaction object, thereby improving the reaction efficiency. As shown in FIG. 3, in this embodiment, the rotary shaft 220 is provided with only one stirring blade 250, but alternatively, the rotary shaft 220 may be provided with two or more stirring blades 250 have. For example, a stirring blade may be additionally provided at the upper end of the rotating shaft 220.

3, the control unit 500 may be provided in the form of a control box. Although not shown, a plurality of configurations for controlling the user may be provided in the form of an operation switch, an operation button, .

The operation of the above-described biodiesel manufacturing apparatus 1 will now be described with reference to FIGS. 6 and 7. FIG.

6 shows a state in which the enzyme trap 230 rises as the driving motor 300 and the rotating shaft 220 connected to the driving motor 300 rotate in the first direction. FIG. 7 shows the driving motor 300 and the rotating And the enzyme trap 230 descends as the shaft 220 rotates in the second direction (the opposite direction to the first direction).

As shown in Figs. 6 and 7, the enzyme trap 230 repeatedly reciprocates between the above-mentioned rising limit point and the falling limit point in the container main portion 100A of the reaction container 100. [ At this time, the biodiesel material in the vessel main body 100A passes through the enzyme trap 230 in a direction opposite to the direction in which the enzyme trap 230 moves, and during the passage of the enzyme, Is contacted and catalyzed by it from fat decomposition.

The fat-decomposing catalytic action causes the fatty acids, which form a part of the biodiesel feedstock, to be decomposed into fatty acids and glycerol, and the degraded fatty acids are combined with the alcohols constituting a part of the biodiesel feedstock to produce FAAE (Fatty Acid Alkyl Eester) is generated. As described above, methanol or ethanol can be applied to the alcohol.

When the biodiesel production reaction is completed, the object (biodiesel) in the reaction vessel 100 is discharged through the discharge port 150 and collected in another container. If necessary, the biodiesel discharged and collected from the reaction vessel 10 may undergo subsequent processes such as washing (washing) and moisture drying to improve its purity.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the present invention can be changed.
