## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to Chinese Application No. 201120292310.7, filed on Aug. 12, 2011. The Chinese Application is incorporated herein by reference in its entirety.
FIELD OF THE INVENTION
The present invention relates to the field of packaging and delivery, in particular to food processing equipment, specifically to a material container for ultra-high pressure food processing.
BACKGROUND OF THE INVENTION
Ultra-high pressure food processing is referred to after placing food in a container, then placing the container in an ultra-high pressure food processing chamber, filling up the chamber with liquid usually with water continuously to make the pressure inside the chamber reach above 100 MPa, usually 6000 atmosphere pressure, to kill the bacteria in the food. The material container disclosed in the prior art is a simple frame, which can not utilize the most of its inner space for placing food, and the process of placing food is time consuming, labor intensive, and not suitable for in-line operation. In addition, the material container disclosed in the prior art bears low pressure only and it is likely to be damaged.
SUMMARY OF THE INVENTION
The purpose of the present invention is to disclose a material container that is suitable for ultra high pressure food processing. Said material container for ultra high pressure food processing is aimed to solve the problems described in the existing technology. For example, the space in the existing material containers can not be utilized effectively for placing food. It is inconvenient for transferring materials in and out of the containers. The existing material containers are not strong enough to bear pressure and they are likely to be damaged.
The material container disclosed in the present application, comprises a cylindrical body which has a window in its side wall, and the window is utilized for putting materials in and taking materials out of the cylindrical body. A first end cover is fixed on one end of the cylindrical body and a second end cover is located on the other end of the cylindrical body. Said second end cover is attached to the cylindrical body by screws. Two or more fluid passage holes are distributed across each end cover respectively. A movable sliding rack is located inside the cylindrical body. The axial direction of said movable sliding rack coincides with the axial direction of the cylindrical body. The movable sliding rack has at least two hollow columns. The axis of any of said hollow columns is in the same direction of the axis of the movable sliding rack. Any two of the neighboring hollow columns are isolated by their wall/walls.
Further, said movable sliding rack includes a center cylindrical tube and six specially sectioned cylindrical tubes. Any one of said specially sectioned cylindrical tubes is comprised of a cylindrical tube having an opening on its wall and the said opening is parallel to the axis of the said cylindrical tube. Said center cylindrical tube is located inside the moveable sliding racking, sharing the same axis with the moveable sliding racking. Said center cylindrical tube is surrounded by the said specially sectioned cylindrical tubes on the periphery, and tangent to the outer wall of each said specially sectioned cylindrical tube. The outer walls of any two neighboring specially sectioned cylindrical tubes are tangent to each other.
Further, both of the first end cover and the second end cover respectively have a carrying handle attached.
Further, in the first end cover, the distribution density of the fluid passage holes increases from the left side of the first end cover to the right side of the first end cover. And in the second end cover, the distribution density of the fluid passage holes increases from the left side of the second end cover to the right side of the second end cover.
The working principle of the present invention is the following. The first end cover and the second end cover have fluid passage holes, which are distributed throughout the first and second end covers. The fluidic passage holes allow water to be added into the cylindrical body in a timely manner. Water leveling at any height along the diameter direction of the cylindrical body can reach into the fluidic passage holes, avoiding damaging on the material container due to the water pressure on the end covers. One end cover is fixed on the cylindrical body and the other end cover can be turned around while it is attached to the cylindrical body by just one screw. By this mechanism, one end of the cylindrical body can be opened for conveniently loading or unloading the materials to be processed, saving time and labor. In one example of the present invention, when processing cup or bottle packed materials, the movable sliding rack is first placed into the cylindrical body, then cup or bottle packed materials are placed into the movable sliding rack. By doing so, the materials can be uploaded or unloaded more quickly and the space inside the cylindrical body can be more effectively utilized than placing the materials inside randomly. In another example of the present invention, when processing bag packed or irregular-shape packed materials, the movable sliding rack can be taken out of the cylindrical body, allowing materials to be placed directly inside the cylindrical body for processing.
Comparing the present invention with existing technology, the material container disclosed in the present invention has positive and obvious advantages. The end covers have multiple fluidic passage holes distributed throughout, which allow water to be timely added into the cylindrical body. Water leveling at any height along the radial direction of the cylindrical body can reach into the fluidic passage holes, avoiding damaging the material container caused by the water pressure on the end covers. Having one end cover fixed onto the cylindrical body, whereas the other end cover can be turned around while being attaching to the cylindrical body with just one screw, making one end of the cylindrical body open, which is more convenient for material loading and unloading, saving time and labor. When cup or bottle packed materials need to be processed, first placing the movable sliding rack inside the cylindrical body and then placing the material into the movable sliding rack, which provides quicker loading and unloading materials. Moreover the space inside the cylindrical body can be utilized more efficiently than placing the materials in randomly. When processing bag packed materials or materials packed in irregular shapes, the movable sliding rack can be taken out from the cylindrical body, and the material can be placed into the cylindrical body directly for processing.
