1 EAST AFRICAN STANDARD Tangential type honey extractor Specification EAST AFRICAN COMMUNITY CD/K/655:2010 ICS EAC 2010 First Edition 2010

2 Foreword Development of the East African Standards has been necessitated by the need for harmonizing requirements governing quality of products and services in East Africa. It is envisaged that through harmonized standardization, trade barriers which are encountered when goods and services are exchanged within the Community will be removed. In order to meet the above objectives, the EAC Partner States have enacted an East African Standardization, Quality Assurance, Metrology and Test Act, 2006 (EAC SQMT Act, 2006) to make provisions for ensuring standardization, quality assurance, metrology and testing of products produced or originating in a third country and traded in the Community in order to facilitate industrial development and trade as well as helping to protect the health and safety of society and the environment in the Community. East African Standards are formulated in accordance with the procedures established by the East African Standards Committee. The East African Standards Committee is established under the provisions of Article 4 of the EAC SQMT Act, The Committee is composed of representatives of the National Standards Bodies in Partner States, together with the representatives from the private sectors and consumer organizations. Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the Partner States. The comments received are discussed and incorporated before finalization of standards, in accordance with the procedures of the Community. Article 15(1) of the EAC SQMT Act, 2006 provides that Within six months of the declaration of an East African Standard, the Partner States shall adopt, without deviation from the approved text of the standard, the East African Standard as a national standard and withdraw any existing national standard with similar scope and purpose. East African Standards are subject to review, to keep pace with technological advances. Users of the East African Standards are therefore expected to ensure that they always have the latest versions of the standards they are implementing.

3 Introduction CD/K/655:2010 The honey extractor is an essential equipment which any bee-keeper should have in order to extract the maximum quantity of honey from the frames. It forms a costly item in bee-keeping equipment. There are many kinds of honey extractors available from simple hand-driven types used in small apiaries to the complex power-driven types used in large beekeeping organizations. This standard prescribes requirements for a hand-driven honey extractor of the tangential type. This type of extractor has two sizes to fit eight super frames of the Type A and Type B beehives specified in CD- K , Beehives Specification. This extractor could also be used for other frames which could fit in the rotating frame-holder of the extractor (set 5.2). In the preparation of this East African Standard, the following sources were consulted extensively: IS 1736:1960(R2002), Specification for Honey Extractor, Tangential Type Codex Alimentarius website: USDA Foreign Agricultural Service website: USDA Agricultural Marketing Service website: USDA Plant Inspectorate Service website: European Union: Assistance derived from these sources is hereby acknowledged.

The Size 1 honey extractor shall be used for all the three sizes of the super frames of the Type A beehive while the Size 2 shall be used for all the three sizes of the super frames of the Type B beehive (see CD/K ). The honey extractor, tangential type, shall be constructed from the following materials: a) Aluminium sheets, rod and wire; b) Galvanized steel sheets; c) Cast iron; d) Mild steel rod, strip and wire; e) Solder; f) Stainless steel sheets; and g) Timber. 5 Construction 5.1 Barrel The barrel of the honey extractor shall be of aluminium sheets (see ISO 6361), galvanized steel sheets (set EAS 11) or stainless steel sheets. It shall be bent and soundly butt welded to form a cylinder. A conical bottom shall be soft soldered (see ISO 9454) to the barrel (see Figure 1). The rims of the barrel shall be rolled over and beaded with mild steel wire of 5 or 6 mm in diameter (see ISO and Figure 1). The beading shall be done in such a way that the wire used is not visible at any point. The joints of the wire shall be properly fused before the beading is done. All the joints and seams shall be soldered properly The spout or honey gate of the barrel shall be fixed in such a position as to enable the barrel to be completely emptied with minimum tilting. The spout shall be soft soldered to the barrel properly. 2 EAC 2010 All rights reserved

This mild steel strip carrying the handle support shall be supported by two steel brackets riveted to the barrel. One end of the first piece of the handle shall have bevelled gear, which shall engage with a bevelled pinion supported on the top of the central shaft. The gear ratio shall be not less than 1: 4. The other end of the first piece of the handle shall be fixed to one end of the second piece of the handle. A wooden grip shall be provided for the other end of the second piece of handle. The handle shall be operated sideways The handle support shall be made of mild steel strip or cast iron (see ISO 3755 and Figure 1) and fixed on the mild steel strip running across the barrel. It shall be provided with holes for the passage of the handle. If the handle support is made of cast iron, it shall be provided with lubricating holes on the top and the inside of the holes meant for the passage of the handle shall be provided with liners. 5.5 Cover There shall be a wooden cover made from any one of the locally available timbers (see EAS 23). The cover shall be made in two pieces to fit the mouth of the barrel and the central frameholder assembly properly. 6 Dimensions The various parts of the two sizes of the honey extractor shall conform to the dimensions shown in Figure 1. 7 Workmanship and finish 7.1 The welding of the honey extractor shall be satisfactory in all respects. The weld shall not be porous or brittle. All welded joints shall be well dressed and smoothly finished. The soldering shall be neat and clean. The honey extractor shall be finished smooth all over.
