The newly discovered skeleton has a history of more than 6,200 years, and scientists have found evidence of the earliest known parasite infection. Archaeologists discovered a parasite egg parasitized near the pelvis in northern Syria, saying it dates back to the first time that ancient societies used crop irrigation systems. Scientists suspect that the new agricultural technology means that people spend a lot of time wading, creating ideal conditions for parasites to enter the human body. This may trigger an outbreak of water-borne flatworm disease, also known as schistosomiasis.

The invention of irrigation was a major technological breakthrough, but flatworm parasites lived in warm fresh water at the time, and tiny worms could penetrate human skin. After growing into adults, they live in the bladder, the intestines and other parts of the body for many years. Symptoms that parasites can cause include fever, rash, abdominal pain, vomiting, and thigh paralysis. Ancient agricultural societies may inadvertently initiate the global spread of flatworm parasites, which cause diseases to millions of people every year. Today, modern irrigation systems continue to spread diseases in developing countries.

Yarn Drying Machine

Yarn Drying Machine/ Package Yarn Steam Dryer adapted the overseas advanced technology. It evaporates the water containing in the package yarn by means of using the little pressed hot air. The hot air cycling system and moist air out letting system enable the rapid drying effects. Yarn Drying Machine is automatic controlled by the computer, it`s easy to operate, the main features are as follows:

- Rapid drying speed

The drying time is about 2.5 hours for one lot, it improves the production. For e.g. with the DB-I serious of 700 pcs package yarn for one lot, the daily production is above 5.2ton.

- High evaporating ability

Based on test of our dryers, the evaporating rate is above 110kg/hour, it`s higher than the 74.9kg/hour of radio frequency dryer, it`s much higher than the traditional hot air dryers.

- Low energy consumption

It adapted the overseas advanced technology, it`s equipped with the hot air cycling and the superior heat insulation system. The main motor is controlled by the inverter, the heating is using the proportional auto control valve, that enables the lower consumption of heat and electricity. The steam consumption kept below 200kg/hour, (i.e. below 0.9ton steam/ 1ton yarn). Electricity consumption is below 50Kw/hour, it`s decreased the drying cost a lot.

- Highly automatic

It`s automatic controlled by computer, which has the 20 programs of A, B model, according to the different technique. It can control temperature, air volume, air pressure and hot air recycling automatically according to the program, it has the alarming and emergency stop system also. The dryer has manual control too, that enables the controllability and chose ability.

- High filter effect

The machine adapted the overseas advanced filter device, the multiply filter function make the air clean rate achieve the requirement. It can avoid the dust and impurity adhesive on the package, so that to achieve the good drying effect, especially for the light color package yarns.
