Overview

Tong manufactures a range of vegetable destoning systems that ensure stones are removed from crop prior to the washing process, in order to prevent any damage to crop or equipment that stones can subsequently cause throughout the vegetable processing line. From Tong’s latest cyclone destoner to economical flume destoners and fully integrated barrel washer destoners, Tong has a destoning solution to suit a wide range of vegetables and waste materials.

Manufactured in a choice of mild or stainless steel depending on your crop, application and specific requirements, Tong crop destoners, often referred to as floatation tanks, are built upon a water-destoning design. The principals of the water-destoning design means that stones sink within to the bottom of destoner’s tank where they can be removed, whilst upward water pressure allows crop to float over and into the washing and processing line.

With Tong’s high quality destoning equipment, stones, clod and other high density materials which may be present within the crop is removed at the beginning of the vegetable processing line, ensuring a high quality end product, whilst increasing the longevity of equipment and minimising downtime and maintenance.

Available as a stand-alone destoner, or integrated within new or existing crop processing facilities, a Tong destoner is a sound investment when it comes to increasing the efficiency and productivity of your vegetable washing processes.

Features

CLOSE-COUPLED DESTONER

CLOSE-COUPLED DESTONER

A close coupled destoner can be fitted to all Tong barrel washers, offering a fully integrated destoner within one washer tank. The integrated barrel washer and destoner allows for effective removal of stones and debris from crop prior to washing. Based on a flume destoning design, an impellor fitted at the bottom of the tank creates an upward pressure on crop, whilst stones drop to the bottom of the tank where they are removed by a heavy duty web elevator. Tong customers who have chosen this option on their barrel washer regularly testify the success of the integrated destoner in their vegetable handling facilities, resulting in no stones passing the handling facility, meaning much less crop and equipment damage, as well as minimising downtime and maintenance.

TPD720 VEGETABLE DESTONER

TPD720 VEGETABLE DESTONER

Tong’s TPD720 destoner offers an effective, compact and low maintenance vegetable destoning system. Built as a stand-alone destoning machine, the TPD720 destoner can be specified as a single machine or integrated within a new or existing vegetable processing line. Featuring a speed-adjustable separation pump in the base of the destoner tank, this destoner works in the same way as the integrated destoner, where upward pressure encourages vegetables to float onto a 700mm wide crop web elevator, whilst stones and debris sinks to the bottom of the tank where a 500mm web elevator effectively removes all waste. The crop web elevator is also fitted with a water spraying system to rinse crop as it is transferred on for processing.

CYCLONE DESTONER

CYCLONE DESTONER

The latest addition to Tong’s destoning equipment range, the cyclone destoner offers exceptionally effective vegetable destoning in which crop enter the conical-shaped tank with circulating water, and similar to tong’s other destoners, crop is carried over the destoning tank whilst stones sink. Based on a simple yet effective design, the cyclone destoner offers a longer residence time for crop in the destoner tank, offering improved separation whilst ensuring low water consumption and minimal maintenance. Available in standard diameters ranging from 1.2m to 3m wide, to suit capacities from 10 to 40 tonnes per hour, the cyclone destoner is an ideal option for high throughput vegetable destoning.

FLUME DESTONER

FLUME DESTONER

Tong’s flume destoner, also known as a fluidised bed destoner, offers effective vegetable destoning to ensure stones and debris are removed from crop prior to washing, preventing crop and equipment damage. Popularly used to destone potatoes and carrots in particular, Tong’s flume destoner can be specified as a stand-alone destoning machine, complete with its own destoning water tank, or it can be specified without a tank for direct connection to a barrel washer. Featuring a stone chute and chevron belted stone elevator, the flume destoner is built with a self-contained pump which pumps water in an upward direction, where crop carries over the water flume and towards the out-feed end of the destoner, whilst stones and debris sink down to the chute and are elevated out of the machine via the stone elevator. A simply designed, affordable destoner that offers effective destoning results.
