The primary core

The beginning of the formation of the core of this company goes back to the year 2010, where a group of undergraduate students started to design and build by defining a research plan and allocating a small budget through one of the research institutes. The first pesticide spraying robot made in Iran was able to detect obstacles and was controlled remotely. The semi-intelligent spraying robot made by this group participated in the science to action domestic festival in 2011 and was ranked 13th among 1368 domestic participants. After the end of the festival, the mentioned group chose the name Arp and proceeded to redesign and upgrade the said robot and prepare it for the festival of innovation and prosperity, which was accepted after the completion of the upgrading process in February 2012. The final was the National Festival of Innovation and Prosperity. Also, the design of the semi-intelligent pesticide spraying robot by the same group was officially registered in 2012 with the number 81798 in the Patent Office of the Land Registry Organization of the country. In 2013, the members of the group became members of the National Elite Foundation due to the ranking of festivals and patents.

Apart from the academic environment

At the beginning of 2013, Arp Group started to design a fully intelligent robot with the ability to receive location-based information in agricultural lands, which was unable to obtain financial support due to the project implementation costs, and since then, it has been on its way to financial independence for Research and development changed. Several obstacles, including the impossibility of using the National Elite Foundation’s duty system facilities due to the foundation’s lack of support for team and group-oriented activities and personal problems kept some members of the ARP group apart for a short time until some Some of the members of the group gathered again after starting their master’s degree in Tehran University and resumed their activities.

A powerful comeback

Before its legal activity, Arp Group made several devices in the form of student thesis and commercial and industrial orders, among which the equipment can be “Citrus orchard irrigation automation system based on closed control and using online data. Meteorology”, “DryZero electric room hot air dryer”, “DryZero 4 cubic meter electric cabinet hot air dryer”, “DryZero gas room hot air dryer” and “System” Controlling the water level of paddy field based on level sensors using solar panels” pointed out.

Painful lesion

In 2017, Arp Group officially started its activity with the legal title of Tosee Pishbord e Samanehaye Khodkar e Arvand Company. The mentioned company operated for one year and obtained some necessary permits in order to fulfill its legal role correctly. In the middle of 2017, a painful incident caused the sudden death of one of the main shareholders of the company, who was also the CEO of the company, and with the follow-up and due to the legal problems caused by this painful loss, the group of shareholders of the company decided to liquidate it.

The Official start

The year 2018 was the beginning of a new era for Arp Group, which by registering a new company with a new name and specifications, entered the field of industry and technology again and continued its activities officially. Tosee Pouyan e Arvand Company was the result of this re-start, with the realization of which Arp Group became a powerful legal group after many ups and downs.


Tosee Pouyan e Arvand Company With the aim of optimizing the processes in which the industry intervenes in agriculture and directs agriculture towards modern agriculture, it has produced five categories of products, which are branded as DryZero, Farmino, Plantino, GrowLi, Agrino and Germino have been launched.

Products Intro


The series of food dehydrator produced by Tosee Pouyan e Arvand is named DryZero. These dehydrators have been launched in the market in two classes, cabinet and room, and with three types of energy sources.

DryZero Room-Class

Hot air dehydrators in the room-class where all the four standards of ASABE/ANSI in the manufacture of hot air dehydrators are met and the quality of the final product is easily suitable for export. These dehydrators have been launched on the market with three types of energy sources: electricity, gas and hybrid (combination of electricity and city gas) and use the most modern automation equipment with the highest precision in control and monitoring. The room-class of DryZero dehydrators gets the highest score in terms of the ratio of the price to the capacity of the device and can be the most economical dehydrators in the market that can compete with global models. Also, in addition to the fact that energy consumption in these dehydrators has been saved as much as possible, the ability of the user to control the amount of energy consumption is also included in these dehydrators.

DryZero cabinet-class

DryZero hot air dehydrators in the cabinet-class are designed in terms of external appearance similar to the best global models of this device, but it has three layers in the body of the dehydrator, which makes the user get the best insulation and the least energy loss in this dehydrators. In the latest tests, these dehydrators have been able to create a temperature difference of 75 degrees centigrade between the inner wall of the dehydrator and its outer wall, which indicates the insulation calculated by taking into account the necessary thermodynamic calculations. Also, one of the other features of this class of dehydrators is their volume variety. These dehydrators have been launched in the market in standard capacities of 2 cubic meters, 4 cubic meters, 8 cubic meters, 16 cubic meters and 32 cubic meters.
