Description

TECHNICAL FIELD The present invention relates to a stirring treatment method and apparatus for coating a solid matter with an adhesive material and stirring the solid matter so as to loosen each solid matter.

2. Description of the Related Art Conventionally, there is an agitation processing device such as that disclosed in Patent Document 1. This agitation processing apparatus coats solids such as nut grains with an adhesive material such as caramel, stirs the solids so as to loosen them, and commercializes roasted nuts coated with caramel.

This agitating device is a vertical rotation-revolution type agitator equipped with a vane-shaped agitator and a rod-shaped agitator, and the vane-shaped agitator and the rod-shaped agitator move against the agitating vessel by rotating and revolving the agitation drive shaft. It is configured to rotate and revolve laterally.

As an example, the roasting of the granular nuts and the caramelization of the granulated sugar put into the stirring vessel are performed by heating the stirring vessel and rotating and revolving the vane-shaped stirrer and the rod-shaped stirrer.

Next, the blade-shaped stirrer and the rod-shaped stirrer are rotated and revolved while solidifying the caramel with cooling of the stirring vessel.

As a result, it is possible to obtain roasted nuts that are caramel-coated while being loosened one by one.

However, such an agitation treatment apparatus performs an agitation treatment in the preceding stage of producing an intermediate product between roasting of granular nuts and caramelization of granulated sugar, and caramel coating in a state in which each grain is loosened while solidifying the caramel. Since the post-stirring process for obtaining the roasted nuts is performed in a single apparatus, there is a problem that the production time is increased from the viewpoint of cleaning.

In other words, caramel and a part of the nuts adhere to the stirring container, the blade-shaped stirrer, etc. after the stirring treatment with heating in the former stage, and then the roasted nuts that have been caramel-coated in the stirring treatment with cooling in the latter stage. Therefore, after the roasted nuts as a product are taken out, the adherents such as caramel and part of the nuts remaining on the inner surface of the stirring vessel and the scraping blade are cooled and solidified.

If batch production is repeated under such conditions, the solidified deposits will be heated again, resulting in excessive caramelization and roasting.

Therefore, if the batch production is repeated, the reheated caramel or the like will be mixed in the intermediate product in the stirring treatment accompanied by heating in the previous stage, and the quality will be affected.

In order to suppress such effects, after taking out the roasted nuts as a product in the later stirring process, it is important to remove the solidified caramel etc. attached to the inner surface of the stirring container and the scraping blade etc. by washing. .

However, after the stirring treatment in the latter stage, it takes a long time to remove the solidified caramel and the like, and there is a problem that the cleaning time is long and the manufacturing time is increased.

In addition, when the high-melting-point adhesive material is transferred to another agitating device or the like for subsequent processing, the growth of such deposits can also occur in a transfer chute or the like where heat such as gas heating is difficult to reach. Therefore, it is also important to suppress the growth of deposits.

It is characterized in that the granular or lumpy solid matter is coated with the sticky material by the stirring treatment in the latter stage and loosened into grains or lumps to obtain the processed material.

Since the present invention is configured as described above, the production of an intermediate processed product by agitating treatment accompanied by heating of the granular or lumpy solid material and the adhesive material in the preceding stage and the agitating treatment accompanied by cooling of the intermediate treated material in the latter stage. can be performed separately in the first and second stirring processing units. For this reason, it is possible to wash and remove the adhesive material before it solidifies in the first stirring section where the adhesive material and the like mainly adhere. Cleaning of the first agitating container of the first agitating processing section and the like can be performed very easily.

At the same time, the control box 26 controls the gas heating device, and the heating of the first stirring vessel 7 is controlled. In this state, the first stirring unit 9 is driven and controlled to heat and stir the raw material in the first stirring vessel 7 to produce an intermediate product.

Next, the heating control of the first stirring vessel 7 and the drive control of the first stirring section 9 are stopped, and the rotation of the stirring head 37 moves the first stirring section 9 to the upper side of the first stirring vessel 7 . is evacuated to

Next, by driving the first hydraulic cylinder device 30, the sub-frame 23 rises and rotates around the rotation shaft 21 as shown in FIG. Due to this rotation, the first stirring vessel 7 is tilted toward the second stirring vessel 11 as indicated by the dashed line.

At this time, in the second stirring section 5 , the second stirring container 11 is tilted in advance with respect to the base frame 62 so as to face the first stirring container 7 side. Such tilting operation is performed by the coordination of the control boxes 26 and 69 . However, the second stirring container 11 can also be tilted in advance by manual operation.

Due to the tilting motion of the first stirring container 7 and the tilting motion of the second stirring container 11 , the opening of the first stirring container 7 is positioned above the hopper portion 61 of the inclined second stirring container 11 . . At this position, the first stirring vessel 7 is inclined slightly downward toward the second stirring vessel 11 .

Due to the downward inclination of the first stirring vessel 7, the intermediate processed material having a high melting point and fluidity in the first stirring vessel 7 is smoothly received from the hopper portion 61 and transferred into the second stirring vessel 11. .

Next, the inclination of the first stirring vessel 7 and the inclination of the second stirring vessel 11 are returned, and cooling water is supplied from the water supply section to the fluid jacket 71 through the water supply pipe 73 . In this state, the second stirring unit 13 is driven, and in the second stirring vessel 11, the intermediate processed material is stirred with cooling as a subsequent stirring process.

The conventional special-purpose machine proposed by the applicant of Patent Document 1 uses a mist cooling method instead of a cooling method using cooling water (jacket cooling method) for cooling because gas heating is involved in heating. This mist cooling method has a lower heat transfer rate than the cooling method using cooling water.

On the other hand, the second stirring vessel 11 of the present embodiment 1 employs a jacket cooling method in which cooling water is supplied to the fluid jacket 71 for cooling. can.

In the stirring process in the second stirring vessel 11, the intermediate processed material is stirred and rotated in the vertical direction by the stirring rotation of the scraping blade 65, and the sticky material coated on the solid material is cooled and solidified to form grains or clumps. It is possible to obtain a processed material that is loosened every time.

At this time, since the stirring rotation in the second stirring vessel 11 is not in the horizontal direction but in the direction of gravity, the solid matter scraped up by the scraping blade 65 falls inside the second stirring vessel 11, and the surface is The coating can facilitate the separation of the gradually solidifying solids from each other.

When continuous batch production is performed, similar operations are continuously performed.

Both the first and second agitation processing units 3 and 5 are cleaned after production is finished. In particular, in the first stirring processing section 3, it is necessary to clean the inside of the first stirring container 7 or the first stirring section 9 by removing sticky materials and solids adhering thereto.

During this cleaning, since the adhesive material is not solidified, it can be easily dissolved and removed with hot water in a short period of time.

Washing water remaining in the first stirring container 7 after washing can be drained without difficulty by tilting the first stirring container 7 toward the spout 15 as indicated by the chain line in FIG.

That is, the first stirring vessel 7 is alternately switched between the transfer mode by tilting toward the second stirring vessel 11 and the cleaning mode toward the spout 15 on the opposite side of the second stirring vessel 11 . Thus, it is possible to transfer the intermediate treatment material from the first stirring vessel 7 to the second stirring vessel 11 and drain the cleaning water from the first stirring vessel 7 .

In the second stirring section 5, since the stirring process is accompanied by cooling, most of the sticky material adheres and solidifies to the second stirring vessel 11 and the second stirring section 13 after the processed material is taken out. After a simple wiping clean, it is ready for the next cooling and solidification process.

The cleaning of the first stirring processing section 3 can be performed during the stirring processing in the second stirring processing section 5, and the cleaning time in the first stirring processing section 3 affects the manufacturing time. You can also choose not to. However, the cleaning of the first and second stirring units 3 and 5 can also be performed after the production of the processed material is completed by the stirring processing in the second stirring processing unit 5 .

<recipe>
・20 kg of nuts (room temperature: 20 degrees Celsius)
・Granulated sugar ・Water ・Additives

<Procedure>
<Caramelization/Roasting>
(1) Caramelization/roasting Add granulated sugar and water to a stirring pot (2) Ignite the gas heating device and start stirring with the rotation-revolution type multi-shaft stirrer Dissolve the granulated sugar and boil down.
(3) Caramelization/Roasting Add additional solid nuts to the stirring pan.
(4) Roast the nuts and caramelize the sugar by adjusting the wall temperature of the stirring pot.
(5) Extinguish the fire (proceed with caramelization and roasting of nuts with residual heat).
(6) Stop stirring, flip up scraping blades, etc., and tilt the stirring pan.
(7) Transfer the intermediate processed material to the cooling/solidifying machine.

Thereafter, cleaning of the stirring pot in the preceding stage is performed during the cooling and solidification process in the subsequent stage, and the operation returns to (1). When cleaning the stirring pot, hot water is poured into the stirring pot to dissolve and remove the remaining intermediate treated material. Since this dissolution removal is performed in a state in which the caramel, etc. is not solidified, the caramel, etc. in the stirring pot dissolves in the hot water in a short period of time. The washing water in the stirring pot can be drained by tilting the stirring pot and easily washed. That is, washing the first agitation processing section 3 at a high temperature facilitates washing.

<Cooling and solidification>
(8) Receiving the intermediate product transferred in cooperation with (7) into the cooling/solidifying machine.
(9) Start agitation of the cooling/solidifying machine.
(10) Cooling water is gradually supplied to the jacket of the cooling/hardening machine to slowly lower the temperature of the caramel and the wall temperature of the cooling/hardening machine. (The degree of slowness was determined in advance by experiment.)
(11) Appropriately put the additive into the cooling/solidifying machine (while cooling from the jacket side).
(12) After the cooling is finished, the supply of cooling water and stirring are stopped, the cooling/solidifying machine is tilted, and the cooled caramel nuts are taken out from the cooling/solidifying machine.
(13) Clean the cooling/solidifying machine. However, there is little adhesion of the product to the wall surface, and the product can be used next time. Since minute solids such as fragments of the processed material (product) remain on the vessel walls and scraping blades, after wiping off and cleaning, prepare for the next cooling and solidification operation.

This procedure resulted in roasted nuts with mostly granular nuts and a caramel coating.
