Abstract: Reduction of contamination and the proportion of fines fractions in the packaging of rod form polysilicon is achieved by directly filling a plastic bag with polysilicon from a cleaning bowl by a rotating motion which causes polysilicon chunks to slide into the bag.

Abstract: Accurate and repeatable portioning of polycrystalline silicon chunks without excessive generation of fines is accomplished by separating silicon chunks into a multiplicity of weighed portions and combining at least four portions which together closely match a target weight into a plastic shipment bag which is then closed.

Abstract: A method of automatic packing of comminuted silicon includes providing an inner bag in a first shaping vessel, spreading out an opening of the inner bag and positioning the opening above a lip of a first filling funnel of a filling unit, and filling the inner bag with comminuted silicon. The comminuted silicon passes through the filling funnel into the inner bag. The inner bag is welded in a welding unit. The opening of the inner bag is folded together by inward folding of two opposite inner bag sides such that two inner bag edges formed by the folding-together are opposite and parallel to one another and form a fold with a channel. A vacuum welder is applied to the fold and welds the inner bag. The inner bag is transferred into an outer bag. The outer bag is welded.

Abstract: The invention relates to a process for packaging polycrystalline silicon in the form of chunks, including the following steps: (a) providing polycrystalline silicon in a metering system; (b) filling polycrystalline silicon from the metering system, which removes fines by use of screening, into a plastic bag arranged below the metering system. The weight of the plastic bag with the polycrystalline silicon introduced is determined during the filling step and the filling step is ended after the attainment of a target weight. A fall height of the polycrystalline silicon from the metering system into the plastic bag is kept at less than 450 mm by use of at least one clamp apparatus over the entire filling step.
Abstract translation: 本发明涉及一种以块状封装多晶硅的方法，包括以下步骤：（a）在计量系统中提供多晶硅; （b）从计量系统填充多晶硅，通过使用筛分将细粒除去放入计量系统下方的塑料袋中。 在填充步骤期间确定引入多晶硅的塑料袋的重量，并且在达到目标重量之后结束填充步骤。 通过在整个填充步骤中使用至少一个夹紧装置将多晶硅从计量系统落入塑料袋中的落下高度保持在小于450mm。
