Abstract
A method of preparing and storing a free-flowing frozen supplementary product, including preparing a supplementary composition for freezing, dripping the supplementary composition into a freezing chamber, freezing the dripped supplementary composition into beads, and transporting the frozen beads by conveyor belt out of the freezing chamber.
Claims12
A method of preparing and storing a free-flowing frozen supplementary product, comprising the steps of:
- preparing a supplementary composition for freezing;
- dripping the supplementary composition into a freezing chamber containing a refrigerant therein;
- freezing the dripped supplementary composition into frozen beads upon contact with the refrigerant, the frozen beads including a plurality of frozen beads of greater than a predetermined size and a plurality of frozen beads of less than the predetermined size;
- draining a product comprising the frozen beads and the refrigerant from the freezing chamber into an intake to an elongated housing, the intake being connected to the freezing chamber, wherein the product exits the freezing chamber and enters the intake prior to entering the elongated housing;
- receiving the product from the intake into an intermediate portion of the elongated housing, the elongated housing having a lower end and an upper end, the upper end being elevated relative to the lower end, wherein the intermediate portion of the elongated housing is between the upper end and the lower end at an intermediate elevation relative to the elevation of the lower end and the elevation of the upper end, the elongated housing further comprising a channel defined within the elongated housing between the lower end and the upper end, wherein the product received from the freezing chamber through the intake contacts a lower portion of a conveyor belt having a mesh surface, the conveyor belt being mounted within the channel adjacent to the intermediate portion for movement between the lower portion and an upper portion within the channel, the upper portion being at a higher elevation than the lower portion, the upper portion being adjacent to the upper end of the elongated housing, wherein a retaining wall defined by the elongated housing from the lower portion to the upper portion is positioned at a straining distance from the mesh surface of the conveyor belt, the straining distance being sized to physically limit movement of the plurality of frozen beads of greater than the predetermined size from the intermediate portion to the lower end of the channel, whereby the plurality of frozen beads of greater than the predetermined size are corralled at the lower portion of the conveyor belt;
- moving the conveyor belt with the product in the elongated housing from the lower portion to the elevated upper portion, wherein the refrigerant in the product in the elongated housing cools the channel within the elongated housing to a temperature below the freezing point of the supplementary composition, whereby the frozen beads in the product in the elongated housing are maintained in frozen form within the channel as the conveyor belt moves from the lower portion to the upper portion;
- sifting the plurality of frozen beads of less than the predetermined size from the frozen beads in the product in the elongated housing and straining the refrigerant from the product in the elongated housing through a plurality of gaps defined in the mesh surface of the conveyor belt as the conveyor belt moves from the lower portion to the upper portion, the mesh surface being sized to enable the plurality of frozen beads of greater than the predetermined size in the product to remain on the mesh surface of the conveyor belt and enable the plurality of frozen beads of less than the predetermined size and the refrigerant in the product to pass through the mesh surface of the conveyor belt as the conveyor belt moves between the lower portion and the upper portion;
- and
- discharging the plurality of frozen beads of greater than the predetermined size on the conveyor belt at the upper portion by dropping the frozen beads of greater than the predetermined size from the upper portion of the conveyor belt into a chute adjacent to the upper end of the elongated housing.
