Open indirectly heated double-walled vats
Double-walled open vats · Topoloveni steam-jacketed vats
Topoloveni's open vats use steam through a double wall and anchor stirring. DoR reports four double-wall copper cauldrons imported from France for early production; their date and the material of current vats are unknown.
The vessel in its documented setting
The name describes a heating arrangement rather than one standard commercial model: an open vat has a second wall around its product-holding body, and steam circulates in that intervening jacket. The EU specification for Magiun de prune Topoloveni says the plum pulp is concentrated by boiling in open, double-walled vats, heated by steam passing through the double walls. It describes this as the local method and contrasts it with vacuum concentration.
The sources also distinguish historical from current material. DoR reports that four double-wall copper cauldrons were imported from France for early Topoloveni magiun production. The article does not date their import or first use, and it does not establish that present-day vats are copper. A linked manufacturer image here is only a broad visual comparison for the open, jacketed vessel form.
Steam between the walls; an anchor in the pulp
Indirect heating separates the product from the heating medium: steam travels through the jacket rather than a flame acting directly on the pulp. The product specification says the vats have anchor stirrers that keep the pulp continuously homogeneous to prevent sticking and caramelisation. DoR's 2010 factory report separately describes wooden paddles turning in the double-wall bain-marie kettles. The records document anchor stirring and wooden paddles, but do not prove that a particular wooden paddle was itself the anchor stirrer.
The job is concentration. Water leaves the plum pulp during the open cook, while continuous movement helps keep the thickening mass from adhering at heated surfaces. The EU specification says the method is not performed under vacuum. Its process details belong to the protected product method, not to a general instruction for operating any jacketed kettle.
A Topoloveni association, not an origin claim
The equipment is documented here through its use in making Magiun de prune Topoloveni, whose production area is specified in the EU record. Local production history reaches further back than the direct equipment description: the EU application cites local archives for a magiun factory founded in Topoloveni in 1914. DoR reports four double-wall copper cauldrons imported from France for early production, without dating the import. Neither fact dates the first use of the precise vessel form described in the current product specification.
DoR's 2010 factory report provides the clearest dated description of the apparatus itself, including wooden paddles and an early-production account of copper cauldrons. Sonimpex's current account describes bain-marie vessels with double walls and steam circulating between them, but does not specify their material. The specific equipment's manufacturer, acquisition route and care instructions remain undocumented in these sources, so this entry identifies a working form and its setting rather than a purchasable specification.
History
DoR reports four double-wall copper cauldrons imported from France for early Topoloveni magiun production, but does not date their arrival or first use. The factory's 1914 establishment is product-history context, not an exact date for these vessels. The exact double-wall vat form is directly described at the factory by 2010 and by the producer today.
Equipment details
PowerNot established The specification identifies steam as the heating medium circulating through the vat walls, but does not identify how steam is generated or give a power connection for the vessel.
How you get oneNot established The sources describe the equipment in a named production method but do not identify a maker, model, supplier or way to acquire an equivalent vat.
CareThe inspected sources do not give cleaning, inspection or maintenance instructions for the vats. Use the equipment maker's documentation for any real installation; this entry is descriptive, not an operating manual.
Made of
- Copper — historical vessel body
DoR reports four double-wall copper cauldrons imported from France for early Topoloveni magiun production, without dating arrival or first use. Current vats' material is unspecified. (https://www.dor.ro/mix-de-prune-magiun-topoloveni/) - Wood — stirring paddles
DoR describes wooden paddles turning in the factory kettles in 2010. It does not establish that these paddles were the same construction as the anchor stirrers in the EU specification. (https://www.dor.ro/mix-de-prune-magiun-topoloveni/)
Risks and precautions · Standard risk
The sources describe steam circulating in a double wall but provide no pressure rating or installation and operating instructions; do not infer safe operating limits from this description or illustration.
Limits
The described form is tied here to the Magiun de prune Topoloveni method. The sources do not establish a universal design, material, size, capacity, pressure rating or other manufacturer's specification.

Documented use · Locality evidenceEU specification ties the product method to its defined geographical area. DoR describes the vats at the Topoloveni factory in 2010; the producer currently describes double-walled bain-marie vessels. This is a documented-use association, not a manufacture or origin claim.
