farm: collecting pollen from the second part

Pollen is a perishable product because of its moisture content, resulting in part from the environment, partly from the hive and by the same method of collection.

Bees, to hold together the microscopic pollen grains during the harvest and moistened with nectar or honey, before you press them in the basket located in the hind legs. The sugars in the pollen is impregnated are hygroscopic and therefore

it tends to take moisture from the environment. Moisture promotes degradation phenomena and that is why the pollen, just recovered from the drawers of the traps must be dried quickly while maintaining a low temperature, excess heat may ruin some active ingredients that make it particularly beneficial.

The forced hot air dryer is an excellent tool for the drying of the pollen, there are several models on the market size and variable cost.

E 'possible and even easy enough to build it, adjusting its size to the real business need. A model suitable to receive the harvest of about two hundred traps is shown in the photos. It 'made with phenolic plywood (also called marine) of 15 mm in thickness which can be easily cut with a jigsaw also unprofessional, the pieces are held together by glue and lag bolts, the sky is made with an metal end of the type used for the bottom of the hives and the closure is made with clips of the type trunk. The shelves are made of a wooden frame made from strips of 20 x 25 mm held by metal brackets are screwed and are about 5 cm less deep than the drier, this device allows you to arrange staggered to create a course for the hot air that is forced to lick the surface of each shelf containing the pollen to a depth of about 1.5 cm, before leaving the sky and the bottom of the shelves is made with a thick plastic mosquito netting secured with a stapler.

The hot air is provided by a ventilated small space heater, the type used to heat small rooms, set on the front wall of the dryer,

;

need to do some testing to find the right combination of fan speed and heating of the help of a thermometer and keeping in mind that the air must not exceed 45 ° C. People who are more familiar with electric circuits, you can place a thermostat that acts on the circuit regulating the operation of the heater. Guideline to achieve the dryer shown in the photograph is addressed at a cost of about $ 100 dedicating a day of work.

The drying process takes about 24 hours, the pollen waiting to be cleansed of impurities is placed in plastic buckets for food (those for the honey) or in sealed bags and stored in freezer five or six days, this step is necessary to permanently inactivate any moth eggs hatching later that would make the product unsuitable for the sale and consumption. It 's interesting to note that the shift in freezer there avoids the use of pesticides, such as the anhydride solforosa,  permettendoci di garantire al consumatore un prodotto integro oltre che perfettamente conservabile.
