Abstract
A cooler for cooling product pursuant to a distillation process, including a first substantially enclosed housing with an inlet proximate a first end for receiving product from a distillation unit, and an outlet proximate a second end for discharging cooled product, and a first auger substantially enclosed within the housing for driving the product from the inlet to the outlet, the auger having a helical blade circumscribing a perforated central hollow shaft for transmitting cooled gas into the housing to help cool product within the housing.
Claims13
A cooler assembly for cooling product pursuant to a distillation process, the cooler assembly comprising:
- a first substantially enclosed housing with an inlet proximate a first end for receiving product from a distillation unit, and an outlet proximate a second end for discharging cooled product;
- a first auger substantially enclosed within the housing for driving the product from the inlet to the outlet, the auger having a helical blade circumscribing a perforated central hollow shaft for transmitting cooled gas into the housing to help cool product within the housing;
- and
- an exhaust port extending through and sealingly attached to the housing and configured to capture and to allow re-cooling of hot gases produced in the housing from cooling the product proximate the first auger, at a location outside the housing, wherein the exhaust port is additionally configured to recirculate re-cooled gases back to the perforated central hollow shaft.
A process for cooling product after the product exits a distillation unit, the process comprising:
- inserting the product into a first chamber enclosed by a first cooler housing;
- driving the product through the first cooler housing with a first auger having a helical blade circumscribing a perforated hollow shaft;
- injecting cool gas into the first chamber through the perforated hollow shaft of the first auger to mix with the product in the first chamber;
- discharging the cooled product from the first chamber,
- venting gas from within the first chamber in the first cooler housing through a first exhaust port attached to the first cooler housing;
- cooling the gas after it exits the first exhaust port;
- and
- recirculating the cooled gas back into the first chamber through the perforated hollow shaft of the first auger to mix with the product in the first chamber.

- discharging the cooled product from the second chamber;
- venting gas from within the second chamber in the second cooler housing through a second exhaust port attached to the second cooler housing;
- cooling the gas after it exits the second exhaust port;
- and
- recirculating the cooled gas back into the second chamber through the perforated hollow shaft of the second auger to mix with the product in the second chamber.
