[Detailed description of the invention]

[0001]

[Industrial applications]

 The brown sugar is classified into hard lumps and powders, and the present invention relates to the latter powdery brown sugar, that is, an apparatus for producing powdered brown sugar.

[0002]

[Problems to be solved by conventional technology and device]

 In recent years, powdered brown sugar has been re-examined in place of white molasses due to the effect of a healthy food boom, and it has attracted people's attention. As a result, demand for powdered brown sugar has increased, and production has fallen behind.

In order to produce powdered brown sugar, normally, a block of brown sugar is once produced, and the block of brown sugar is crushed or ground to mechanically powder it. In other words, edible lime milk is added to the sugar juice obtained by pressing sugar cane, boiled down, concentrated, and cooled to once produce lumpy brown sugar. And, because this mass of brown sugar is mechanically crushed or ground to form a powder, it is inefficient, takes time to work, and cannot be mass-produced.

Moreover, if the high-density blocky brown sugar is crushed or ground, the particle size of the powdered brown sugar is not constant, and as a result, it does not melt uniformly during use, and in terms of quality I cannot meet your wishes.

The technical problem of the present invention is to pay attention to such a problem, and to realize an apparatus capable of efficiently producing powdered brown sugar, which enables mass production, and has a fine grained and uniform powdered brown sugar. Is to get.

[0006]

[Means for Solving the Problems]

 According to a first aspect of the present invention, there is provided a container for containing the concentrated sugar juice prepared by adding lime milk to the sugar juice squeezed from sugar cane, a means for stirring the concentrated sugar juice in the container, and a blowing means for blowing air into the container. An apparatus for producing powdered brown sugar having ,.

[0007] As described above, when an apparatus for putting concentrated sugar juice in a container and blowing air is used, the concentrated sugar juice is blown with continuous stirring to cool and evaporate water without giving time for the concentrated sugar juice to solidify. As a result, it becomes powdery brown sugar with a fine and uniform particle size.

Further, since powdered brown sugar can be manufactured continuously with the conventional brown sugar manufacturing process, once a mass of brown sugar is manufactured as in the conventional case, it is crushed or ground into powder. Compared with the method, the manufacturing efficiency is remarkably increased and it is suitable for mass production.

According to a second aspect, the stirring means according to the first aspect is a screw having an arbitrary structure, and the screw is connected to a drive source so that the screw can alternate between forward rotation and reverse rotation about its axis. This is a powdered brown sugar manufacturing device.

As described above, the screw for stirring the concentrated sugar juice has a structure in which the forward rotation and the reverse rotation are alternately repeated. Therefore, the concentrated sugar juice stirred by the screw repeatedly rotates and slides back and forth in the container. Therefore, it is efficiently cooled and the water is evaporated. As a result, good quality brown sugar can be produced in a short time.

A third aspect of the present invention is the screw according to the first or second aspect, wherein the screw has a single or a plurality of through holes or spaces between the outer periphery and the central shaft. It is a manufacturing device.

[0012] As described above, when the screw has a through hole or a space, the concentrated sugar juice has a large adhesion area on the screw surface and good ventilation, so that a fine and uniform powdered brown sugar can be produced in a shorter time. .

According to a fourth aspect of the present invention, the screw according to the first aspect, the second aspect or the third aspect is a horizontal type, and a discharge port is opened on a screw end side of a wall of a container in which the screw is installed. It is a manufacturing device for powdered brown sugar.

As described above, when the horizontal screw is stirred, the concentrated sugar juice can smoothly move back and forth, and cooling and evaporation of water can be effectively performed. In addition, since the screw has an outlet on the end side, it is possible to collect powdered products in the outlet and discharge them simply by rotating the screw in the discharge direction after stirring and blowing, which is excellent in workability. .

[0015]

[Embodiment of the invention]

 Next, an embodiment will be described of how the powdered brown sugar manufacturing apparatus according to the present invention is actually embodied. 1 is an embodiment of an apparatus for producing powdered brown sugar according to the present invention. (1) is a plan view, (2) is a sectional view taken along line AA of (1), and (3) is of (1). It is a BB sectional view.

Reference numeral 1 denotes an iron container, which has a U-shaped cross section as shown in FIG. The screw conveyor is configured by incorporating the screw 2 in the U-shaped container 1.

Both ends 4a, 4b of a shaft 4 at the center of the screw 2 are inserted and supported by bearings 3a, 3b fixed to side walls 1a, 1b at both ends of the U-shaped container 1. The chain sprocket 5 fixed to the shaft end 4b and the chain sprocket 7 fixed to the output shaft 6 of the motor M are connected by a chain 8.

A discharge port 9 is opened below one end wall 1a of the U-shaped container 1, and a guide 10 is integrally connected to the outside of the discharge port 9. Further, the discharge port 9 is opened and closed by an opening / closing lid 11 that rotates around a horizontal axis.

The screw 2 may have a structure similar to that of a normal screw conveyor, but in the illustrated embodiment, in order to increase the contact area between the agitated concentrated sugar juice and air and to improve the ventilation, the screw 2 The central shaft 4 is connected with a radial spoke 12, and a space 13 is formed between the screw 2 and the shaft 4.

(2) As shown in FIG. 2, a blower fan f rotatably driven by a motor m is disposed diagonally above the U-shaped container 1 so that air is blown into the U-shaped container 1. I am

In this apparatus, concentrated sugar juice is put in the U-shaped container 1 and blown into the U-shaped container 1 by the fan f. Further, the motor 2 rotates the screw 2 to stir the concentrated sugar juice in the U-shaped container 1.

That is, when viewed from the side of the chain sprocket 5, when the screw 2 rotates counterclockwise, the concentrated sugar juice S in the U-shaped container 1 is moved to the left side in the figure. Further, when the screw 2 rotates clockwise, the concentrated sugar juice S is moved to the right side in the figure.

Therefore, when the screw M 2 is rotated right and left alternately by rotating the motor M forward and backward, the concentrated sugar juice S in the U-shaped container 1 is moved to the left side in the figure, and then The operation of moving to the right can be alternately performed in a predetermined cycle. With such a reciprocating movement, the concentrated sugar juice adheres to the screw 2 and the shaft 4 and slides on the inner wall of the U-shaped container 1 and the concentrated sugar juice rubs against each other. Is stirred repeatedly without allowing time for it to set.

Moreover, the concentrated sugar juice S is cooled and the water is evaporated by the air blow by the air blow fan f. Therefore, it is muddy at the beginning, becomes clay-like as the stirring progresses, then becomes a brittle mass, and finally becomes a powder.

As described above, by continuously stirring and promoting cooling of the blast and evaporation of water without allowing time for the concentrated sugar juice to solidify, fine powdery and uniform powdered brown sugar of high quality can be obtained. To be In order to improve the stirring and cooling effects, it is necessary not to put a large amount of concentrated sugar juice as a raw material in an excessive amount, and it is preferable that the screw shaft 4 is sufficiently exposed.

In the apparatus shown in the figure, the desired powdered brown sugar can be obtained by stirring and blowing air for about 15 minutes, so at the end, the screw 2 is rotated counterclockwise to discharge the powdered brown sugar in the U-shaped container 1 through the discharge port 9 The powdered brown sugar is completed when it is moved to the side, the opening / closing lid 11 is opened, and the guide 10 is transferred to an iron plate tray or the like for cooling.

FIG. 2 is a flow chart illustrating a method for producing powdered brown sugar by the apparatus of FIG. First, as in (1), sugar cane is squeezed, and edible lime milk is added to the squeezed juice to boil it. For boiling, use a single kettle until it becomes concentrated and thick, or use multiple kettles such as Ichiban, No. 2, and No. 3 to gradually transfer to the final stage. There are various ways to boil it, including the most concentrated method in the pot.

The above is the same as the ordinary method for producing brown sugar, but in order to produce powdered brown sugar with the device of the present invention, the screw 2 is placed in the U-shaped container 1 as in (3). The fan is blown with the fan f while rotating it in normal and reverse directions and stirring. This blast stirring process is continuously performed until the concentrated sugar juice becomes powdered brown sugar.

The time required for the blast and agitation treatment varies depending on the amount of raw materials and the agitation treatment capacity of the agitator, but in the examples, in the case of concentrated sugar juice of about 100 kg, the agitation blast for about 15 minutes results in a particle size. A fine and uniform brown sugar powder was obtained.

As shown in FIG. 1, when a space 13 is formed between the outer circumference of the screw 2 and the central shaft 4, the air flow from the blower fan f is good, and the screw 2 is in contact with the air. Since the area is large, the contact area of the concentrated sugar juice with the screw 2 is large, and cooling of the concentrated sugar juice and evaporation of water are promoted.

In order to enhance the cooling effect, the blower fan f may be a cool air blower that blows cold air generated by an air conditioner or the like. It is also possible to form the screw 2 with a metal tube, and put cold air or cold water therein or circulate it. It is also possible to form the shaft 4 with a hollow tube and pass cold air or cooling water through it.

FIG. 3 shows another embodiment of the screw, in which a screw 15 is formed on the outer circumference of the drum 14. Therefore, the concentrated sugar juice adheres also to the outer peripheral surface of the drum 14, and by sliding on the inner wall of the U-shaped container 1 and rubbing the concentrated sugar juice with each other, the concentrated sugar juice can be stirred without solidifying time. . The rotation speed of the screws 2 and 15 may be a low speed of several tens to 100 rotations per minute.

When the drum 14 is constantly air-cooled by sending air into the drum 14 from one opening as shown by the arrow and discharging it from the other opening, cooling of the concentrated sugar juice is further promoted. It is also possible to send the cool air generated by the air conditioner into the drum 14, and it is also possible to send the cooling water. Also in these cases, it is preferable to use the blower fan f in combination.

As described above, the powdered brown sugar can be produced by rotating the screws 2 and 15 in the forward and reverse directions for, for example, about 15 minutes, but in order to produce a larger amount, as shown in FIG. The production capacity can be increased by arranging the letter-shaped containers 1 in parallel and adjoining each other and providing the screw 2 therein. It is possible to automate the production by setting the forward rotation and reverse rotation periods of the screws 2 and 15 and the stirring time with a timer.

In order to speed up the cooling of the concentrated sugar juice in the U-shaped container 1 and increase the production efficiency, the U-shaped container 1 is cooled by blowing air from the outside or water cooling the U-shaped bottom or side wall. Is also effective.

Further, the screw conveyor mechanism has been exemplified as the stirring means for the concentrated sugar juice, but various stirring mechanisms other than these can be used.

[0037]

[Effect of the invention]

 When a device for putting concentrated sugar juice in a container and agitating and blowing is used as in claim 1, the concentrated sugar juice is blown and cooled with continuous stirring and the moisture is evaporated without giving time for the concentrated sugar juice to solidify. As a result, it becomes a powdery brown sugar with a fine particle size and uniform.

Further, since powdered brown sugar can be manufactured continuously with the conventional brown sugar manufacturing process, once the mass of brown sugar is manufactured as in the conventional case, it is crushed or ground into powder. Compared with the method, the manufacturing efficiency is remarkably increased and it is suitable for mass production.

According to the second aspect of the present invention, the screw for stirring the concentrated sugar juice has a structure in which the forward rotation and the reverse rotation are alternately repeated. Therefore, the concentrated sugar juice stirred by the screw rotates and slides and reciprocates in the container. By repeating the above, the cooling is efficiently performed and the water is evaporated. As a result, good quality brown sugar can be produced in a short time.

When the screw has a through hole or a space as in claim 3, a large area for adhering the concentrated sugar juice to the screw surface and good ventilation are achieved. Can produce sugar.

By stirring with a horizontal screw as in claim 4, the concentrated sugar juice can smoothly reciprocate, and cooling and evaporation of water can be effectively performed. Also, since the screw has an outlet on the end side, powdered products can be collected and discharged at the outlet simply by rotating the screw in the discharge direction after stirring and blowing, which is excellent in workability. .
