Jua-Kali

The mixer has a capacity of 1.5 m3 and can mix 50 kg of feed at a time. It is manually driven by using a well designed handle. It can also be adapted to be operated by a gasoline engine or electrical power. J. Kariuki, Sagana, demonstrates.

he feed experiment (opposite top left) has taken an interesting direction by delving into so-called appropriate technology. Two important pieces of equipment, a pelleter and a mixer, have been successfully developed. The two were developed with the help of an informal sector, locally known as Jua-Kali, and are designed to meet local needs for easy service and maintenance.

Jua-Kali is a local name which literally means "hot sun," and is given to enterprises that work with metal and wood materials. The industry, though small in scale, plays an important role in the livelihoods of many Kenyans. The Jua-Kali sector makes good, inexpensive tools and equipment from scrap metal and with limited resources. The history of the Jua-Kali in agriculture development in Kenya is well known and is well represented in the production of agricultural tools and equipment.

Most of the Jua-Kali equipment in the agricultural sector meets the designs and specifications of the sector. Up until now the aquaculture sector has not benefited much from the industry. The turnaround came earlier in this current work plan, when Jua-Kali was engaged to develop a pelleter and mixer. The two have attracted the attention of farmers with two of them placing orders for the pelleter and many others venturing into making their own mixers.

The pelleter resembles a meat mincer and is driven by a single phase 1.5 hp motor. It was developed in collaboration with the engineering company East African Foundry Works in Nairobi. The first of its kind to be made by local artisans, it has a capacity to produce approximately 30 kg pellets of feed per hour. J. Kariuki, Sagana, is pictured.
