Abstract

PURPOSE:To perform sufficient mixing of tea leaves by using a rotary drum consisting of a cylindrical or polygonal tubular drum having a charging and discharging door on the side wall and rotating the drum around the diagonal line, thereby vertically and laterally shaking the mixing object. CONSTITUTION:A rotary drum 1 having cylindrical or polygonal tubular form is rotatably supported on a machine frame 3 with a shaft 2 fixed to both ends of the drum 1 with a flange and is rotated by a motor 9 in a state inclined relative to the horizontal shaft 2. The side plate 4 is provided with a charging and discharging door 7. The door is operated by an air cylinder 8 and the mixing object is charged into the drum by a charging conveyor 10.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention is applied to a machine for mixing brown rice tea, rough tea, sencha, etc.

(0) Prior art The conventional TtR881 has a cylindrical drum mounted on a machine frame around a central axis, and a rotation mechanism is provided on the drum. Dry it and put it into the drum from the input port.
The mixture to be mixed is introduced and the drum is rotated. Then, the materials to be mixed are tilted at a constant inclination angle within the drum, and while maintaining the Uif5, the upper part of the mixture is successively lowered by 1 to perform mixing.

(8) Problems to be solved by the invention However, at this time, the mixed object 11 near the central axis! is difficult to mix because it is always below the surface.As a means of mixing this, some devices have 11 placed inside the drum, but since 11 is placed parallel to the 6 wheels, the rotation of the drum Even if there is sufficient mixing in the axial direction, there is almost no mixing in the axial direction.As a result, the mixing time is very short and the efficiency is poor.In addition, the product may become white due to II Ill N, and its shape may be damaged. As a result, the product value decreases.

Therefore, Book 1 If @ Ming is tea production without the above drawbacks: I! The purpose is to offer unity.

(d) Means for Solving the Problems In order to achieve the above-mentioned purpose, this book describes a rotating cylinder that is cylindrical or polygonal and is installed so that it can freely rotate six times around a diagonal line, and A loading/unloading S is provided on the side wall of the barrel.

(N) Embodiments Figures 1 to 3 show embodiments of the invention S.
Reference numeral 1, the modification of which will be explained based on these drawings, is a regular hexagonal cylinder with 9 cylinders, and is pivotally supported on the machine frame 3 by six shafts 2 fixed to both lines thereof.

Since the six axes 2 are fixed on the diagonals of the left and right a-plates 4.5 of the rotary drum 1, the rotary drum 11 is inclined with respect to the six horizontal axes 2. In addition, the 6-shaft 2 does not pass through the inside of the one-rotation cylinder 1, and the left and right side plates 4.
Il rare. The left side plate 4 is equipped with a s7 that serves both for loading and unloading. The rs door 7 is opened by an air cylinder 8.

When adding the M mixture, when @7 is directly above the @turn I
f111 & stopped, the door 7 is opened by the air cylinder 8, and the material is fed by the feeding conveyor 10.

Then close 117 with air cylinder 8
The mixer is rotated at a speed of 2 to 3 rpm by the drive of .

Condition of the mixture at the time of mixing 'lFr! 52 At dawn, s7
In the vicinity of a in Fig. 1, where the WT is located above, those with large specific gravity are deposited in the lower layer, and those with smaller specific gravity are deposited in the upper layer. Then, as the part a moves upward while rotating, the upper layers fall diagonally downward first, and when 1117 falls downward, they are mixed together and deposited near part b. In this way, the materials to be mixed are sufficiently mixed by the lever that repeatedly moves vertically and horizontally.

Next, when taking out the mixture, use the air cylinder 8 to open the door 7.
% gap, rotate the rotary cylinder 11 & 9 and take out the tJ from the trough 1
The mixture to be taken out above 1 will be deposited near a when s7 is in the upward position W, so even if ji7 is left open, it will not spread and spill from the rotary cylinder 1, and the door 7 will be in the downward position. Since it will fall when it is removed, it will surely be taken out onto the trough 11.

The time required for mixing is: I! It varies depending on the JL type of the old item, but it is 5 to 15 rotations [degrees], and in terms of time it is 2 to 15 rotations [degrees].
It takes about 5 minutes.

Figures Ml to 2 show that the rotary cylinder 1 is a regular hexagonal prism, but in the case of a cylindrical cylinder such as M3Ua, which may be cylindrical, 4112 is not provided because the mixture is easy to slip. If it does, it will not slip and will be sufficiently raised and mixed.

Incidentally, the loading door and the unloading door ff1I may be provided separately, but if they are used together as in this embodiment, horizontal installation becomes easier and cheaper.

A) The invention's GH result is the rotation of a cylindrical or polygonal M cane +111
is pivoted at the center of its diagonal m%, so when rotating the rotary cylinder 1, it receives, I! The mixture moves up, down, left and right, and is thoroughly mixed. Therefore, it is mixed in a very short time, and 5! There are almost no scratches, the product is free from white smearing, and the product value is increased. Also, it only takes a short time, so make it in one go! Efficiency will also improve.
