Allpax Helps Canneries Boost Retort Room Capacity with No Additional Floor Space Required

Canneries utilizing swing-open door retorts can expect capacity increases from 8 to 33 percent by installing Allpax orbital door retorts. By taking advantage of the wasted floor space occupied by existing swing-open doors, the Allpax orbiting door retorts allows the plant to lengthen the working shell by one basket per door.

COVINGTON, LA – Allpax, powered by Pro Mach, said today canneries can increase production capacity with no additional plant real estate required. Canneries that replace old swing-open door retorts with Allpax orbital door retorts can expect capacity increases from 8 to 33 percent, depending on the current basket capacity of the retort room.

Allpax orbital door retorts rotate up thus using floor space more efficiently than retorts with the swing-open configuration. Allpax personnel will conduct cannery audits that examine and report on cost effective ways to expand capacity and productivity as well as lower energy costs and water utilization. The goal is to add years of higher capacity production to the cannery and to improve the overall sustainability of the operation. 

The following chart illustrates the typical range of capacity expansion to expect from projects that replace swing-open door retorts with new Allpax orbital door retorts.

Allpax helps to improve the environmental footprint of the cannery with energy and water savings

The Allpax cannery auditor will also examine energy and water usage and prepare a cost/benefit analysis of incorporating Allpax energy and water savings technology introduced in 2015. The new Allpax water saver system reduces the cost of water disposal and usage by up to 50 percent, while making free hot water available for plant operations. This cooling water recovery technology gives canneries the ability to use the hot water from a standard water spray retort cycle during the first stages of cooling to capture hot water, and then in the second stages of cooling to contain the warm water and use it in the next cycle instead of disposing of it.

The Allpax waste-heat recovery technology captures steam in a vented tank where it condenses into hot water. This water can be used to supplement hot water in lavatories and cleaning stations or it can be run through heat exchangers for heating food or other processes at the plant. Canneries may be eligible for state and federal tax benefits when these systems are incorporated into the operation.
