Grain Storage G rain storage  on a  subsistence farm  is primarily based on minimizing grain loss. In modern agricultural practices there are methods of managing less than 1% grain loss, but small subsistence farms can see 20% - 100% of grain loss. This causes starvation and an unstable food supply. Grain loss can be caused by mould growth, bugs, birds, or any other contamination. One method of preventing loss is hermetic grain storage. Hermetic grain storage strives to eliminate all exchange of gases within the storage system. This mitigates bacterial activity and prevents rodents and bugs from being able to breathe inside the storage systems. The introduction of hermetic grain storage to subsistence farms can create a more stable food supply in the area and reduce the risk of starvation.. Requirements for safe storage Crops left standing un-harvested start to show diminishing quantitative and qualitative returns through shatter losses and attacks by insects, m...

Introduction This kind of hand and manual corn sheller is a small kind of agricultural machine for threshing corn seed from corn cob.It is reliable and safe,for it is not control by the power, it is more convenient in using,simple structure,high rate of threshing.it is suitable for small farm using.

1. Function   To shell groundnut pods and separate kernels . 2. Specification (i) Overall dimension (L x B x H, mm)   600 x 350 x 700 (ii) Capacity   200 kg/h (ii) Power required     Manual 3. General Information     It consists of an oscillating sector with sieve bottom and a handle. Number of cast iron peg assemblies are fitted in the oscillating sector unit.  The groundnut pods are shelled between the oscillating sector and the fixed perforated concave screen.  The decorticated shells and kernels fall down through the perforated concave sieve.  The kernel and husk are collected at the bottom of the unit and separated amnually ...
