THE INFLUENCE OF HAMMERS` PERIPHERAL SPEED ON THE PERFORMANCE OF THE HAMMER MILLS

Cereal milling is a complex process resulting in a wide variety of particles that differ in size, surface or composition. Ensuring a rational regime regarding the technological process of hammer mills operation, actually refers to the correlation of the indices to ensure the functioning of the mills at optimal values. The peripheral speed of hammers is one of the decisive factors in the milling process. Speed limitation is determined by fodder resistance, the construction of working parts and their durability. In the paper we study the influence of hammers` peripheral speed on the product subjected to milling, through a series of experiments under exploitation conditions

RESEARCH OF THE MAIN PROCESSING WORKS FOR ESTABLISHING A JERUSALEM ARTICHOKE CROP ON DIFFICULT AND CONTAMINATED SOILS

Jerusalem artichoke, is a technical plant that have some special features which make it suitable to be cultivated on degraded and difficult soils. However, processing difficult lands can cause major problems for farmers, in terms of using the right technology and reducing investment costs. The paper aim to address to the main challenges faced in preparing the soil for a Jerusalem artichoke culture, in order to maximize the productivity and efficiency

USE OF DETACHING EQUIPMENT IN GRAPE POMACE PROCESSING TECHNOLOGY

The equipment is intended to operate within the fruit processing technological flows, respectively to detach- disintegrate the grape pomace which are formed during the fruit pressing using milling drums. These pomaces, usually are made up of fruit solid agglomerations, that have a greater seed concentration and humidity, especially when the rotary rollers are working with a certain distance between, in order to not crush the grape seeds. Based on these considerations, in the paper it is analyzed and presented the case in which the detacher can successfully be used in grape seeds separating technology from the pomace and its performances to separate the sub-products resulting from the grapes pressing operation

CONSIDERATIONS ON ENERGETIC CROPS POTENTIAL

In order to breathe fresh and clean air, nature and terrestrial atmosphere should be preserved and protected. Carbon emissions represent one of the main enemies of air quality. Recently, carbon emissions have surpassed all the predictions because the excessive industrialization, becoming the determining factor for global warming. A viable alternative to carbon emissions reduction is the utilization of energy sources that can diminish the noxious substances emissions up to zero. This can be done by using the power of wind, sun, water, energy plants, etc. Among the energetic potential plants, the biomass is obtained- a form of renewable energy which final product is biofuel

CONSIDERATIONS REGARDING THE HARVESTING TECHNOLOGIES OF JERUSALEM ARTICHOKE

Jerusalem artichoke (Helianthus tuberosusL.) is not cultivated on the large surface that cereals, vegetables or potatoes so mechanizes technologies are not very often encountered. In this paper are presented few technologies used on the country where this culture occupied large surface and not only

EQUIPMENT FOR EXTRACTING AND PLANTING EARTH BALE ROOT PLANTS

Trees are one of the biggest  organisms living on the planet and their role is extremely important, namely that to maintain the purity of air we breathe, improve water quality, prevent soil erosion, reduce noise level, ensure food, construction materials and eventually people comfort. Plantation and transplantation of trees by means of specialized equipment  in comparison with human force leads to an increased planting speed and higher yield, economically speaking. This paper is designed to present different constructive variants, at world level, of equipment for extracting and planting trees with earth bale at their roots, necessary for afforestation, landscape design, tree nurseries

CONSIDERATIONS ON THE EXTRACTION TECHNOLOGY OF SUGAR SORGHUM JUICE

Lately there has been an increase in drought periods but also an increase in population and therefore in consumption of food and fuel while arable land remains the same which leads to the cultivation of species with high energy potential and high nutritional potential as drought resistant, species of sorghum. The sorghum is used for: food (flours, juices, syrups, vinegar, etc.), for animal feed, but also in the industry for fuel, energy, building materials, paper, proposes to carry out an analysis of the technologies for obtaining juice from sorghum
