Possibility and necessity of tartaric acid production in the Republic of Moldova

Abstract

For tartaric lime obtaining, a conventional method is proposed. Drinking water at room temperature is mixed with the solid-type tartaric raw material (in the case of liquid material, the washing step is unnecessary). The diffusion juice of raw material is mixed with CaCO3 introduced to the mixing chamber. Treatment can be repeated several times in the same vessel to accumulate calcium tartrate. Then, the tartaric lime is washed with water, dried, and transferred to the tartaric acid production plant. The washed pomace can be used for further seed separation or as an addition to animal feed, compost, and others.
