Various embodiments described herein relates to techniques for providing real-time productivity information to a worker in a material handling environment. In this regard, for computing a productivity metric of the worker, a productivity metrics system may access various types of data. In this aspect, the productivity metric system may receive: order level data associated with multiple items identified for shipping; worker operation data associated with the workers and at least one workflow being operated by the workers; and dimensional data of the items being handled by the workers. The productivity metric system may compute the productivity metrics of the worker based on: the order level data, the dimensional data, the worker operation data, and a count of items handled by the worker. Further, the productivity metrics system may provide notifications including actionable insights indicative of actions to be performed by the worker.

A conveyor belt (36) is arranged in at least one spiral conveyor unit (32) or (34) is arranged in tiers forming at ascending spiral stack (38) and/or a descending spiral stack (40). A ceiling or top sheet (58) is positioned over the spiral stack. A circulation fan (60, 62) draws spent thermal processing medium laterally from the tiers of the spiral stack, up the exterior of the stack and across the top of the stack above the ceiling or top sheet and through a heat exchanger (64) located above the ceiling. The treated thermal processing medium is then routed across the remainder of the diameter of the spiral stack and then down the side of the spiral stack diametrically opposite to the circulating fan thereby to enter the spiral stack in a lateral direction diametrically toward the circulating fan. At least one opening (70, 100, 200) is formed in the ceiling between the heat exchanger and the diametrically distal end of the spiral stack from the circulating fan thereby to provide an alternative flow path for a portion of the thermal processing medium to enter the spiral stack from above, thereby resulting in more uniform treatment of the work product being carried by the conveyor of the spiral stack.

A material handling system includes a conveyor, an actuation unit, and a chute. The chute is mechanically coupled to the conveyor at a defined angle with respect to a surface of the conveyor. The chute includes an inlet defining a first end and a second end, where the first end of the inlet is mechanically coupled to the surface of the conveyor. Further, the chute includes at least one tube configured to be rotated by the actuation unit at a defined rotational speed. The chute also includes an outlet mechanically coupled to the at least one tube. In this aspect, the defined angle and the defined rotational speed is based on at least one of: physical characteristic of an item to be passed through the chute, a rate of inflow of the item through the inlet, and a rate of outflow of the item through the outlet.

A disclosed food processing assembly includes a plurality of food processing units. Each unit is configured to convey food product arriving at an ingress point to an egress point. The assembly includes rotary valves configured to transfer food product from the egress point of one unit to the ingress point of a subsequent unit while maintaining environmental isolation between the two units. A programmable electronic controller is configured to monitor environmental parameters within each unit and to generate control signals provided to various resources to maintain environmental parameters within each unit at a distinct set of value. The resources may include air compressors, steam generators, vacuum pumps, and the like. In this manner, the assembly enables a multi-step food process to proceed essentially continuously with little or no delay between sequential process steps despite with each step being associated with a distinct set of time, temperature, pressure, and humidity values.

The invention relates to a positive drive spiral conveyor which includes, a drive tower rotatable about a vertical axis and a plurality of drive members extending in length from a bottom to a top of the drive tower. The drive members are spaced radially around the drive tower, with each drive member having a projecting driving ridge extending in length along at least a section of each drive member with a projecting shaft positioned on each drive member proximate an end of the driving ridge thereby defining an engagement zone. The projecting shaft defines a guiding surface around the shaft, such that in use a positive drive protrusion of a conveyor belt engages the guiding surface of the projecting shaft and is guided towards a leading side of the driving ridge.
