IIR BIOGAS TECHNOLOGY
Description and Characteristics
Biogas is a combustible gas produced by anaerobic fermentation of organic materials by the action of methanogenic bacteria. The most important constituent of Biogas as fuel is methane (CH4). Methane is odorless and invisible in bright daylight. It burns with a clear blue flame without smoke and is non-toxic. It produces more heat than kerosene, wood, charcoal, and cow-dung chips. Institute of Industrial Research has developed two types of biogas plants; the floating metal dome digester and a fixed brick dome digester. The organic matter for Biogas production in Ghana include cowdung, straw, human feces, poultry manure, pig manure and water hyacinth. KVIP’s can have biogas technology incorporated to treat the waste and also generate biogas. The organic matter is mixed with water to form a slurry of an appropriate concentration. Waste from food and beverage industries can also be used for biogas generation.
Mechanized Palm Kernel and Shall Operator
Description and Characteristics
The palm kernel – shell separator is designed to separate cracked palm nuts into various components. Its design combines two distinct separation techniques into a compact single unit. These units are a rotary screen cylinder and an inclined belt conveyor. The rotary screen is made up of two concentric galvanized iron wire mesh screens (an inner and outer screen), rolled with a taper. This assembly is mounted on a shaft through which power is transmitted. The rotary screen is more or less a cleaning device designed to remove all the debris and fine particles and at the same time sort the cleaned mixture of kernels and shells into two size ranges. The output from the screen is deposited on to the conveyor belt assembly. As the material moves up the incline, separation takes place.
INTEGRATED CASSAVA PROCESSING

Description and Characteristics
The Integrated Cassava Processing Pilot Plant is designed to process 10-25metric tones of fresh cassava tubers into traditional fermented derivatives including gari, kokonte, agbelima vis-� -vis relatively new product of unfermented high quality cassava flour. Another unique feature of the plant is the incorporation of an animal feed processing unit that converts the cassava peels into animal feeds supplements to promote rearing of goats, sheep, cows etc. Three main machine incorporated into traditional process techniques to ensure production of unfermented high quality cassava flour are dryer for drying the sieved fine dough into flakes, hammer mill for milling and sieving the dried flour flakes and sifter to capture and finally sieve and grade the finely milled unfermented high quality cassava flour.

TWIN OR SINGLE HYBRID ENERGY SAVING STOVES
Description and characteristics
The twin or single hybrid energy saving stove is an improvement over existing traditional stoves with emphasis on the mode of air flow to facilitate combustion and enhance efficiency.  It consists of the following units:
  1. Basement
  2. Air inlet coupled with air flow facilitator
  3. Fuel inlet
  4. Fire box with perforated/drilled fire grate
  5. Chimney
The firebox unlike traditional stoves is raised and seated on a basement/platform with an opening called air flow facilitator. Outside air flows through the air flow facilitator and bottom of the firebox where the perforated fire grate is located and out through the chimney. The firebox is made of hollow burnt bricks and formed in a circular manner to a pre-defined height.  The hollow bricks are finally filled with insulation materials like ashes.  The insulation enhances good combustion and hence guarantees maximum utilization of the heat generated. This stove is energy efficient, and enhance clean cooking.
