Introduction

<sup>Drum dryers are used in the food industry for drying a variety of products, such as milk products, baby foods, breakfast cereal, fruit and vegetable pulp, mashed potatoes, cooked starch, and spent yeast.

In a drying operation, liquid, slurry, or puree material is applied as a thin layer onto the outer surface of revolving drums that are internally heated by steam. After about three-quarters of a revolution from the point of feeding, the product is dried and removed with a static scraper. Factors affecting the rate of drying and final moisture content are residence time on the drum; surface temperature and film thickness.

A drum dryer consists of one or two horizontally mounted hollow cylinder(s) made of high-grade cast iron or stainless steel, a supporting frame, a product feeding system, a scraper, and auxiliaries.

Typical structures of single and double drum dryers are shown in Fig. 1. The diameter of typical drums ranges from 0.5m to 6m and the length from 1m to 6m. In operation, steam at a temperature up to 200°C heats the inner surface of the drum. The moist material is uniformly applied in a thin layer (0.5mm-2 mm) onto the outer drum surface. Most of the moisture is removed at water boiling temperature. The residence time of the product on the drum ranges from a few seconds to dozens of seconds to reach final moisture contents of often less than 5% (wet basis) (Tang, et.al., 2003). The energy consumption in a drum dryer may range between 1.1 kg steams per kg of evaporated water and1.6 kg steam per kg of evaporated water, corresponding to energy efficiencies of about 60%-90% (Hall, 1986; Moore, 1995).</sup>

Installation and Commissioning and Training:

1. Buyers arrange installation and debugging by themselves under a manual book from the supplier.

2. If the buyer requires engineers from the seller's party, the buyer should arrange the following items:

(A)Within 30 days after the machines are delivered to the buyer's factory, the buyer shall inform the seller to arrange engineers to the buyer's factory for installation, commissioning, test, and training machine operators.

(B)The buyer should provide the engineers(1-2 person) the boarding and lodging, transportation during the engineer's stay in the buyer's country, and round trip air ticket and visa fee for the engineers. Besides, the buyer should pay the money as salary for one engineer per day.
