Abstract

PURPOSE:To provide a culture apparatus having excellent operability and safety, by attaching a culture tank at the lower front part of a casing, attaching a storage tank of conditioning solution to the right or left side of the upper front part of the casing and attaching the operation devices to the part opposite to the storage tank. CONSTITUTION:The culture tank 11 is attached to the lower front part of the casing, and the storage tanks 12-14 are placed to the upper front part of the casing at the right side of the center line A. The operation boards 15, 16 are arranged to the upper front part of the casing at the left side of the center line A. The operation devices can be shielded from the heat of the flame generated in the supply of conditioning liquid to the storage tanks 12-14 by this arrangement.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a culture apparatus 11c in which equipment and a control device necessary for culture are attached to one housing.

[Background of the invention]

Various culturing apparatuses used for fermentation, culturing of microorganisms or cells, etc. have been developed and sold. Among these, a culture tank with a relatively small capacity and a liquid P to be supplied to this culture tank are installed on the front of one housing.
Storage tank for storing acid, alkaline solution for HIII cleaning, antifoaming solution for extinguishing foam generated in the culture tank (hereinafter collectively referred to as adjustment solution), and operation of culture in the culture tank. There is a known device that has a control device for the operation.

However, the existing culture! In devices, the mutual arrangement of devices attached to the front of the housing does not take operability and safety into consideration. That is, in most cases, operating equipment is placed above a storage tank for storing liquids such as PH14 regulators, but this causes the following inconveniences. When supplying the adjustment liquid to each storage tank, it is necessary to do this in an aseptic manner, and for this reason, the upper part of each storage tank has a function of generating a large amount of liquid. For example, as shown in FIG. 2, in the upper part of each storage tank 24, fill a groove 22C made of metal fittings 2C with cotton 23, soak the cotton with methyl alcohol, etc., and then set it on fire. There are no items installed that can cause fire hazards if turned on.

supplying the adjustment liquid into the storage tank 24, generating a flame;
This flame sterilizes bacteria in the air while the adjustment liquid flows into the storage tank, preventing bacteria from entering. However, due to this occurrence, the operating equipment installed above is easily affected by the heat, which may lead to malfunction. Further, when supplying the adjustment liquid, the operation using the operating device is substantially difficult.

The technology for culturing using a culture tank is disclosed in Japanese Patent Application Laid-open No. 1986-
No. 98085, Japanese Unexamined Patent Publication No. 58-78584, and others.

[Purpose of the invention]

The object of the invention is to provide a culturing* device that is optimally arranged in consideration of operability and safety.

[Summary of the invention]

The uninvented method is to install the culture tank below the front of the housing, and adjust it above the front of the housing to the right or left of the center! ! It is characterized in that a storage tank for storing the liquid is attached, and a device for operation is attached to the side opposite to the side where the storage tank is attached.

[Embodiments of the invention]

Hereinafter, a detailed explanation will be given with reference to a specific embodiment shown in FIG.

In this figure, %10 is a housing, on the front of which a culture tank, storage tank, and operating equipment are attached, and inside contains control equipment and the like that operate according to commands from the operating equipment. 1 is a culture tank, into which a culture medium and materials to be cultured (microorganisms and cells) are supplied to carry out suspension culture. 12 to 14 are storage tanks. Specifically, I2 is a storage tank for storing acid for pH adjustment, 13 is a storage tank for storing alkali for PHIK adjustment,
14 is a storage tank for storing an antifoaming liquid. ] 5 and 16 are operation panels on which operation equipment is centrally arranged. Operation panel 15C
is equipped with a small computer and has a control function to maintain the temperature, pressure, pH, etc. of the culture tank at predetermined values. The operation panel 5 is provided with various keys, a display section, etc. as shown in FIG. In Figure 3, 16
1 is part of the numeric keypad, 162 is automatic 1 manual switching part, J63 is process selection part, ]64 is control function selection part, 165 is parameter selection part, 366 is part of operation keys for manual operation, 167
168 indicates a power switch, and 168 indicates a display.

In other words, the operation panel 15C is used to input data necessary for culture operations, or to select between manual and automatic operations.

Equipment that must be operated frequently by operators will be located.

The operation panel 16 is located above the panel 15 and serves as a recorder.

Items such as sequencers that do not require operator operation during operation are incorporated. In addition, the housing 10 of this culture *device
The size is height H-1800sw+, IIIAW-1
000m@, depth B-60011.

Now, in the culture apparatus shown in FIG. 1, the culture tank 1 is mounted at the bottom of the front of the housing (the top surface of the culture tank 11 is below H/2). This is so that when an operator cleans the inside of the culture tank 11, the inside can be seen visually, and the inside of the culture tank 11 can be made clear during the cleaning work.

Moreover, the storage tanks 12 to 14 are arranged above the front surface of the housing and on the right side of the center position in the width direction of the person. The operation panels 15 and 16 are located above the housing screen, and
It is arranged on the left side of the center position 11A in the width direction. This is to make the operating equipment less susceptible to heat effects caused by the flames generated when the adjustment liquid is supplied to the storage tanks 12 to 14.

Of course, the arrangement of the storage tank and operation panel was reversed (the storage tank was placed in the upper left corner,
The same effect can be obtained by moving the operation panel to the upper right corner). Furthermore, since the amount of operation of the operating equipment by the operator is quite large, the frequently operated items are grouped together on the operation panel 15, and the items that do not need to be operated or are operated infrequently are placed on the operation panel.
6# assembly, operation panel] 5 is installed so as to be located below the operation panel 16. This #1 is to make it easier for the operator to perform the operation, and #1 allows the operator to perform the operation without having to raise his or her arm much. In this example, the center of the operation panel 15 was installed at a distance of 120 (1 wm) from the floor surface, but if the distance is 900 to 1,500 m, there will be no inconvenience during operation.

〔Effect of the invention〕

As explained above, one aspect of the present invention is operability.

A culture device that is superior in terms of safety can be provided.
