Lamb Dryer

The University Malaysia Sabah (UMS) has invented a novel drying technology called the Laterally Aerated Moving Bed (LAMB) Dryer and patented under the name of biomass dryer patent no. F26B 3/04(2006.01) and F26B 3/14(2006.01), IP No. WO 2016/060540A1.


On the 23rd November 2016, UMS has licensed out to Villaco Sdn Bhd exclusively for Malaysia and Southeast Asian regions to commercialise, manufacture and market the LAMB dryer within the exclusive regions.


The advantages of LAMB dryer for paddy drying compare to the existing Inclined Bed Dryer type and other dryers available in the market are:

Good drying uniformity

Less labour intensive

Fly dust and husk free (Environmental Friendly)

Space saver

Low cost (price of product, operation, service & maintenance)

Can be used to dry other round shape materials such as black pepper, palm oil kernel and plastic beads.

A pilot prototype of 2000kg capacity LAMB dryer has been successfully built , tested and commissioned at Kilang Padi Sri Dusun Sdn Bhd, Kota Belud, Sabah for paddy drying.

Main Components:

Dryer Drum

Electrical heater, blower and thermal control panel system.

Loading screw type conveyor

Unloading belt type conveyor

Cyclone dust collector & filter bags

Moisture absorber


LAMB-2000 (Capacity : 2000 kg)

LAMB-1000 (Capacity : 1000 kg)

LAMB-500 (Capacity : 500 kg)

LAMB-250 (Capacity : 250 kg)

Built Materials:

Stainless Steel 304 sheet (AMS 5513, ASTM A240, ASTM A666) for dryer drum

Mild Steel Square Tube (ASTM A513, ASTM A500) for dryer frame.

Average Drying Period:

5 to 8 hours in Paddy drying (Reduce humidity from 27% to 14%)

Product Quality Certification

ISO 9001:2015


Custom made, 12 months warranty , delivery, installation, testing & commissioning, product training and after sales service.

    Figure 1: Schematic Diagram of LAMB Dryer

    Fresh paddy is put inside the paddy feeder (1). Paddy from the feeder will be transferred into the LAMB dryer (3) using a vertical conveyor (2). Air from the LAMB dryer is sucked by the air blower (6) and sent to the air heater box (5) and then the hot air is sent to the LAMB dryer through the upper part of the perforated inner tube. The heating temperature is controlled by a closed-loop temperature control system which uses a thermocouple sensor, whereby the heating capacity of the air heater is adjustable to deliver the desired temperature of the paddy bed monitored by a temperature probe. The system is energy efficient as the hot air is recycled back through the close-loop aeration/air heating system. It minimizes the electrical energy consumption since the hot air is recycled back to the heater. The outer wall of the dryer is made of double walling and fill in between 50mm thick of ceramic fiber fire proof insulation to reduce heat loss through the dryer drum. The moisture content of the paddy is monitored manually through a sampling port on the LAMB dryer. The dried paddy is withdrawn from the bottom of the LAMB using a mechanical conveyor belt.
