Abstract
A particles object freezing device includes an air-permeable belt configured to support conveyance of a particles object, and an injection plate which includes a plurality of injection holes configured to inject a cooling gas for fluidizing the particles object toward the belt from below. The injection plate includes a first injection part and a second injection part which are disposed along a width direction of the belt, and are different in opening ratio. A first boundary between the first injection part and the second injection part is along a traveling direction of the belt.
Claims12
A particles object freezing device, comprising:
- an air-permeable belt configured to support conveyance of a particles object;
- and
- an injection plate which includes a plurality of injection holes configured to inject a cooling gas for fluidizing the particles object toward the belt from below,
- wherein the injection plate includes:
- a first injection part including a plurality of first injection holes among the plurality of injection holes, each of the plurality of first injection holes extending straightly along a normal direction of the injection plate;
- and
- a second injection part disposed adjacent to the first injection part in a width direction of the air-permeable belt and including a plurality of second injection holes among the plurality of injection holes, each of the plurality of second injection holes extending straightly along the normal direction,
- wherein a first opening ratio at which the plurality of first injection holes are formed in the first injection part is different from a second opening ratio at which the plurality of second injection holes are formed in the second injection part, and
- wherein a first boundary between the first injection part and the second injection part is along a traveling direction of the belt.
A particles object freezing device, comprising:
- an air-permeable belt configured to support conveyance of a particles object;
- and
- an injection plate which includes a plurality of injection holes configured to inject a cooling gas for fluidizing the particles object toward the belt from below,
- wherein the injection plate includes a first injection part including first injection holes among the plurality of injection holes and a second injection part including second injection holes among the plurality of injection holes, the first injection part and the second injection part being disposed along a width direction of the belt and having mutually different opening ratios,
- wherein a first boundary between the first injection part and the second injection part is along a traveling direction of the belt,
- wherein the first injection part and the second injection part are independent of each other,
- wherein the particle object freezing device further comprises a support frame to which the injection plate is removably attached,
- wherein the first injection part including the first injection holes and the second injection part including the second injection holes are removably attached to the support frame.
