In Shell Pistachio Processing

All operations that result in: 1. peeling, 2. washing, 3. separating, 4. drying and 5. grading the product are called processing. This operation can be done fully mechanized, semi-mechanized and in a traditional way. In the mechanized method, the processing is done in a very short time, so that the product imported from the garden enters the processed line and the soft skin, clam tail, leaves of the tree and other extra materials are separated and removed from the line. In the next step, the pistachio product is rinsed with clean water, which is used only once, then the separation of the semisolid pistachios and the full reaches are done and placed in a separate place. Afterwards, the pistachios enter the body of the moisture and extra water is taken. Moisture pistachios are introduced into a drying machine that remains at about 60-50 ° C for a relatively long time (about 8 hours).

Good pistachio climate

The pistachio tree is resistant to severe cold winter and high summer heat. Pistachio tree is not compatible with weather and humidity. Humidity in the ground causes gum disease and collapse of the tree, which gradually weakens and finally dries the tree. The pistachio tree shows a high resistance to dehydration and dryness, so that old trees can be kept alive for a long time (maybe several decades) without irrigation.

Botanical profile of pistachio tree

The pistachio tree (Pistacia Vera) belongs to the Anacardiaceae family. The genus Pistacia has 11 species. The pistachio flowers have no petals and mosquito tubers and do not attract honey bees, and the pollen is scattered by the wind. The pistachio tree is a small leaf, it is fallen out and it sleeps the winter.

uThis plant tree is a two-base, namely male and female flowers separated from each other, and each on a separate tree. The pistachio inflorescences are generally clustering, and in the male cluster, the flowers are compressed and dense to each other, more flowers are observed than in the cluster of matter, the distance between the flowers is high on the other, and therefore these flowers form a cluster and a fissure. The pistachio tree sits from 7 to 9 years old and can withstand temperatures of 45 degrees above zero and 25 degrees below zero. It is also resistant to drought and dehydration. Among the different types of pistachio, only pistachio straw species are produced in Iran, and the main areas of pistachio cultivation are concentrated in Damghan, Kerman, Azarbaijan, Qazvin, Ardestan and Rafsanjan.

Picking pistachios

1. Take the pistachio when it is full.

2. Take the harvest early in the early hours of the day and place the harvested product under shade or cool place.

3. Take pest infected areas in a separate garden.

4. Transfer the harvested product to the pistachio processing centers, which are fully automatic and hygienic, to be quickly peeled off and disassembled. In this way, the color of the pistachio hard shell will be of good color and style.

Desirable pistachio soil

The best soils for pistachio seedlings are light limonic soils, sand and clay. It is satisfactory to use fertilizers for harvesting on land, but in areas of heavy clay that hold moisture to a large extent and for a long time, planting this plant does not yield a satisfactory result, and the amount of the product will not be noticeable. Pistachio tree somewhat tolerates soil salinity.
