Preparation Plant for Peas A Tenderometer is an essential instrument for testing the maturity of peas on arrival at the plant, and this should be synchronised for scale readings with the Tenderometer on the farms Areel washer is required to rinse the peas on arrival a pneumatic separator will remove by aspiration any leaf or stalk left in after the farm cleaning. The latter is now usually so good that factory aspiration produces very little extraneous matter. A floatation quality grader will separate the peas into positive quality grades by specific gravity. A typical machine is illustrated A pea pump is an ideal medium for conveying peas from process to Process in water. The rotor of the pump should be specially designed to minimise damage and, although several makes are available, the author has found that the Mono pump is very satisfactory. Special tough glass piping is used for the conveying medium. A recycling tank is fitted with a grid for separating out the peas and returning the water Preparation Plant For Beetroot In addition to the hitherto mentioned washing and cleaning plant for roots, beets require complete cooking before drying There are two alternatives: (a)standard autoclaves batch fed or( b)a Thermoscrew at I bar (atm)pressure, giving a throughput of up to 2 tonnes per hour continuously on a 20 to 40 minute cycle Preparation Plant Common to All Products Steam pans, stainless steel, jacketed, capacity 400 litres, with electric stirrer, are used for making up additive solutions for the blancher or for the sulphite applicator spray(see illustration of integrated unit) a dewaterer for removing surface water from products immediately before entry into the dryer. This can be used as a sulphite applicator as well by incorporating a water sparge pipe over the reciprocating deck Services and Utilities TABLE 3.2 lists the power, steam and water consumption required to service the principal items of preparation plant in a medium/large sized dehydration factory.

Preparation Plant For Beetroot In addition to the hitherto mentioned washing and cleaning plant for mots, beets require complete cooking before drying. There are two alternatives: (a) standard autoclaves batch fed, or (b) a Thermoscrew at 1 bar (am) pressure, giving a throughput of up to 2 tonnes per hour continuously on a 20 to 40 minute cycle.
